Moving Day is a puzzle in Professor Layton and the Unwound Future.

Puzzle

Two men are moving boxes from the first floor to the third. The larger man can carry two boxes at a time, and it takes him one minute to get to the third floor. The smaller man can carry only one box at a time, but it takes him just 30 seconds to make it to the third floor. For both men, the return trip to the first floor is the same as the trip up.

If there were seven boxes total, how many minutes would it take the men to get all the boxes to the third floor?

You can get the answer by calculating everything out, but it's a lot easier to visualize if you use the Memo function. After one minute has passed, how many boxes have been moved?
And where are the locations of the two men at that time?

After a minute is up, the larger man has carried two boxes up and the smaller man has carried one. The larger man is still upstairs, though, while the little guy has made it back down to the first floor.

If this is the case, what's their progress after two minutes?

At the end of two minutes, the larger fellow has made it down to the first floor again and is ready to bring up some more boxes. The little guy has brought another box upstairs, for a total of four boxes on the third floor. That means there are just three boxes left to move.

In the earlier hints, you learned that after two minutes have passed, four boxes had been brought upstairs and both men were back down on the first floor.

If it takes 30 seconds for the little guy to get upstairs with one box, and the larger fellow can make it upstairs with two boxes in a minute...

Solution

Incorrect

Too bad!

Rather than just working the puzzle out in your head, try making notes on the picture using the Memo function.

Correct

Correct!

It would take three minutes to get all the boxes to the top floor. This puzzle gets a lot easier if you draw a diagram.
