Reasoning and answer: He runs the race in 5 / 15 = 1 / 3 of an hour. So he runs the race in 60 / 3 = 20 minutes. That means he beat the next fastest guy by 23 - 20 = 3 minutes.
The answer: 3

The perimeter of the garden is 2 * 225 + 2 * 125 = 450 + 250 = 700 feet. Minus the two gates, he will need at least 700 - 3 - 10 = 687 feet of fencing.
The answer: 687
Reverse engineering the question: Bob is building a garden on his land, and he wants it to be fenced in to keep out varmints. The garden is a rectangular plot 225 feet long by 125 feet wide. He also wants to have a small 3-foot wide gate to walk through and a larger 10-foot wide gate to move his gardening equipment through.

Reasoning and answer: He traded in the SNES for 150 * .8 = $120. Including the money he gave, he spent 120 + 80 = $200. He got 10 + 30 = $40 in change. So the NES cost 200 - 40 = $160.
The answer: 160

At the end of the day, he had tested 120 boards, each with three tacks, for a total of 3 * 120 = 360 tacks. He had 30 tacks remaining in each of the three cans, for an additional 3 * 30 = 90 thumbs tacks. Therefore, the original total combined number of thumbtacks in the three full cans of thumbtacks was 360 + 90 = 450 thumbtacks.
The answer: 450
Reverse engineering the question: Lorenzo put three full cans of thumbtacks into his pocket and went off to work at the corkboard factory. It was Lorenzo's job, as head of quality control, to test every cork board for its ability to hold thumbtacks. He placed one thumbtack from each of the three cans of thumbtacks into every board tested. At the end of the day, he had tested 120 boards and had 30 tacks remaining in each of the three cans. What was the total combined number of thumbtacks from the three full cans?


Reasoning and answer: The total ratio representing the revenue Lucille has is 4 + 11 = 15. The value from the ratio representing employee salary is 4 / 15, and this is 4 / 15 * $3000 = $800 that Lucille has to pay her employees.
The answer: 800
