Puzzle 139

Name: Coast to Coast

Picarats: 70

Description: A woman boards a nonstop flight leaving Los Angeles at noon and arrives in New York City at 8 p.m. The next day, the same woman leaves New York at noon and flies back to Los Angeles. The flight is unaffected by jet streams and takes the same amount of time to reach its destination as it did the previous day. The time difference means it is always three hours earlier in New York than in Los Angeles. Can you figure out what time the plane arrives back in Los Angeles? Give your answer in 24-hour notation.

• Hint 1: Think about the rotation of the earth. The time in locations farther to the east is ahead of that of more western locales. Therefore, given a three-hour time difference, when it's noon in Los Angeles, it must be 15:00 in New York.
• Hint 2: Taking into account the time difference, the plane left Los Angeles at 15:00 New York Time and landed at 20:00. Therefore, the flight itself must have taken five hours.
• Hint 3: The time difference has a reverse effect on the flight returning to Los Angeles. If the plane to Los Angeles left New York at noon New York time, you could also say it left New York at 9 a. m. Los Angeles time.

Answer

14:00

Puzzle 140

Name: One Extra Block

Picarats: 70

Description: The diagram below shows a structure made of 28 blocks. Of these blocks, 27 form a neat larger cube, and on top of that sits a single block poking out above the rest. Below this diagram sit those same 28 blocks, but this time the cube had been separated into five chunks. Tap the chunk, A through E, that contains the single block that sat on top of all the others. Assume that all five chunks fit together as shown and can't be rotated from their current orientation.

• Hint 1: If the top block on chunk D were the block you're searching for, then the block on the bottom-left corner would stick out of the cube. D must not be the correct answer. Remember, each chunk is locked in its current orientation and can't be rotated.
• Hint 2: If the block you seek was at the top of C, then D would be forced out of the structure when all the chunks were put back together. Chunk C must not be the answer either.
• Hint 3: Chunk D forms a part of the front-left side of the large cube. Use that information to start reconstructing the structure in your head. As the pieces come together, the answer should be clear.

Answer

B contains the top block.

Puzzle 141

Name: Disappearing Act 6

Picarats: 99

Description: Just as before, you can move any ball in the board below just as long as it satisfies the following conditions:

• To move, jump your selected ball over an adjacent space occupied by another ball into an empty space on the other side. You can't jump diagonally.
• Once you've made the jump, the ball you jumped over disappears from the board.
• To complete the puzzle, you must remove all balls from the board except for one.

OK enough rules, start getting rid of those balls!

• Hint 1: You have quite a few balls to get rid of, so you'll have to do a lot of jumping. Just make sure you aren't choosing your moves at random, or you'll end up getting stuck before you finish. Plan out your jumps so that you never leave any balls out away from the group where you won't be able to reach them later.
• Hint 2: As you reduce the number of balls on the board, those remaining take on a configuration that you've previously solved. If you've made it this far, this puzzle is in the bag for you.
• Hint 3: Sorry, there are no more hints to be had for this puzzle, You may have heard that proper peg solitaire players don't consider these puzzles complete unless the remaining ball ends up in the center space. One step at a time, though. Let's finish this puzzle first.

Answer

Jump the middle ball on the second column right, then jump the leftmost ball in the second lowest row up. Jump the bottom ball in the leftmost column right, then jump the second from the left ball in the third lowest row left. Jump the bottom ball in the second from the right column left, then jump the right ball in the bottom row up. Jump the second lowest ball in the third from the right column down, then jump the left ball in the bottom row right. Jump the lowest ball up, then jump the second lowest ball in the third from the left column down. Jump the top ball in the third from the left column down, then jump the right ball in the second highest row down. Jump the middle ball in the third from the right column down, then jump the right ball in the lowest row left. Jump the lowest ball up, then jump the lowest ball in the third from the left column up. Jump the top ball in the leftmost column down, then jump the leftmost ball right. Jump the lower ball in the third from the left column right, then jump the top ball in the rightmost column left. Jump the middle ball in the third highest row to the right, then jump the bottom ball in the rightmost column up. Jump the rightmost ball left, then jump the right ball in the top row left. Jump the top ball down, then jump the leftmost ball right. Jump the middle ball in the middle column right, then jump the top ball in the rightmost column down. Jump the rightmost ball to the left, then jump the lowest ball up. Finally, jump either balls over the other to solve the puzzle.

Puzzle 142

Name: The Scholar's Life

Picarats: 60

Description: The following words are written on a famous mathematician's grave. "Following the 1/6th of my life I spent as a child, I spent 1/12th of my life as a young man. Then, 1/7th of my life later, I got married. Five years after I was wed, I was blessed with a child, but sadly, he only lived half the time I was alive before passing away. Today, four years after his death, I too will depart from this world." Can you use these words to figure out how many years the mathematician lived?

• Hint 1: Try rigging up a linear equation where this mathematician's life in years equals x.
• Hint 2: Would you rather not use hard math to solve this puzzle? Have no fear--you can also solve this puzzle without using a linear equation. By adding together 1/6, 1/12, 1/7, and 1/2 of this man's life, you can express the length of the mathematician's life as fractions, minus the parts that were five and four years long. You can find the answer using only this information.
• Hint 3: The lowest common denominator of 2, 6, 7, and 12 seems to be the same as the length of the mathematician's life expressed in years.

Answer

84 years. The mathematician's age can be expressed as 1/6x + 1/12x + 1/7x + 5 + 1/2x + 4, where x is the number of years the mathematician has lived. Using this formula, you can easily work out his age.

Puzzle 143

Name: Letter Calculations

Picarats: 60

Description: If you take the problem 11*11=121, and replace the 1s with As and the 2s with Bs, you get AA*AA=ABA. Using that same replacement idea, you can also generate AA*AA=BBCC. New values may or may not have been assigned for each letter. Can you figure out what A, B, and C equal in the above equation?

• Hint 1: Each letter is represented by a single-digit number, so the possibilities for what number represents each letter are fairly limited.
• Hint 2: If you start by subbing in 1 for A and work your way through all the other numerical possibilities for A, you'll find your answer before long. What's more, if you use a calculator, trying out every possibility will only take a minute or two. But if you can, try to solve it just using your head.
• Hint 3: As detailed in Hint Two, if you substitute every digit for A and work your way up, you'll find the answer in the last half of your search.

Puzzle 144

Name: Super Pancakes

Picarats: 99

Description: Now here's a tasty puzzle for you. You task is to take that big stack of pancakes on the left plate and move them to the plate on the far right. In doing so, however, You need to follow these rules:

• You can move only one pancake at a time.
• A pancake can never rest on another pancake smaller than itself.

Feel free to shift things around as much as you like and to use the middle plate in completing the puzzle.

• Hint 1: The method for solving pancake puzzles has been described in many other hints. Move the smallest pancake over to the middle plate, then move the next-smallest pancake to the right plate. Then stack the smallest cake on top of the one on the right. Next, take a new, slightly larger pancake from the stack on the left and move it onto the open middle plate. Read more on what to do next in Hint Two.
• Hint 2: From where Hint One left off, put the smallest pancake on the pancake sitting on the middle plate. Then move the pancake on the right plate over to the stack on the left. Bring the smallest pancake you have over to sit on top of the stack of pancakes on the left plate. You can solve this puzzle by repeating the process outlined in Hints One and Two while introducing bigger and bigger pancakes, but it's not very efficient.
• Hint 3: Aim to limit the number of moves you make to keep yourself from getting confused along the way.
