## Puzzle

US Version

Create a valid equation by placing a number (1,2 4, 5, 6, 8, 9) into each box (A, B, C, D, E, F, G).

In this puzzle, the two digits to the left of each colon are minutes, and the two digits to the right are seconds. Sixty seconds will roll over into a minute, and you can't exceed 60 minutes.

UK Version

For starters, what do you know for sure? Well, you know that the answer time ends in seven and the top time is multiplied by three, so the number that goes in box D must end in seven when multiplied by three! There's only one that will work. It's an odd number.

To start with, what do you know for sure? Well, you know that the bottom time ends in seven and the top time is multiplied by three, so the number that goes in box D must end in seven when multiplied by three! There's only one that will work and it's an odd number.

US Version

Nine times three ends in seven. So the nine goes in box D.

Two times three is six, so what does that tell you about what number goes in box A?

UK Version

Nine times three gives a number ending in seven. So the nine goes in box D.

Two times three is six, so what does that tell you about what number goes in box A?

US Version

If the number in box A is greater than one, the lower value will exceed 60 minutes, which isn't allowed. Therefore, the one must go in box A.

If you think carefully about the rest, you should figure it out. Here's another hint, though: the five goes in box E.

UK Version

If the number in box A is greater than one, the time will exceed 60 minutes (one hour) when multiplied by three. The puzzle mentioned that 60 minutes cannot roll over into an hour so the one must go in box A.

Think carefully about the rest and you should be able to work it out. Here's one more tip though: the five goes in box E.

US Version

The one, four, eight, and nine all go in the top time.

The rest can be calculated from there.

UK Version

The one, four, eight and nine all go in the top time.

The rest can be calculated from there.

## Solution

### Incorrect

US Version

Calculating time isn't quite as simple as it might seem at first.

UK Version

Calculating time isn't quite as easy as it might seem at first.

### Correct

Correct!

US Version

The equation 18 minutes and 49 seconds times three equals 56 minutes and 27 seconds. That wasn't to hard, right?

Nine is the only single-digit number that will produce a seven when multiplied by three, so it's the only possible choice for box D. Also, if the number in box A was any larger than one, the answer would exceed 60 minutes, which isn't allowed in this puzzle. The rest can be calculated step by step.
