Jim ran 16 miles in 2 hours while Frank ran 20 miles in 2 hours. How many more miles did Frank run than Jim in an hour? Give the rationale and then the answer.
Let's think step by step. Jim ran 16 / 2 = 8 miles for an hour. Frank ran 20 / 2 = 10 miles for an hour. Frank ran 10 - 8 = 2 more miles than Jim in an hour.. The answer is: 2.

There are 100 people in a theater. If 19 of these people have blue eyes, half of them have brown eyes, a quarter have black eyes, and the rest have green eyes, how many of them have green eyes? Give the rationale and then the answer.
Let's think step by step. 100 / 2 = 50 people in the theater have brown eyes. 100 / 4 = 25 people in the theater have black eyes. There are 50 + 25 + 19 = 94 people in the theater with either brown, black, or blue eyes. There are 100 - 94 = 6 people in the theater with green eyes.. The answer is: 6.

James has a rainwater collection barrel. For each inch of rain he collects 15 gallons. On Monday it rained 4 inches and on Tuesday it rained 3 inches. He can sell water for $1.2 per gallon. How much money did he make from selling all the water? Give the rationale and then the answer.
Let's think step by step. It rained 3 + 4 = 7 inches. So he collected 7 * 15 = 105 gallons. So he makes 105 * 1.2 = $126 from selling the water.. The answer is: 126.
