Answer the following question.
Erin works in the school cafeteria serving soup. Each bowl of soup has 10 ounces, and Erin can serve 5 bowls per minute. If the pot of soup has 6 gallons of soup, how long will it take Erin to serve all the soup, rounded to the nearest minute? (There are 128 ounces to a gallon.)
Step-by-step reasoning process: First find the number of ounces Erin serves per minute: 10 ounces / bowl * 5 bowls / minute = 50 ounces / minute. Then find the number of ounces in the pot: 6 gallons * 128 ounces / gallon = 768 ounces. Then divide the total amount of soup by the amount of soup Erin serves per minute: 768 minutes / 50 ounces / minute = 15.36 minutes, which rounds down to 15 minutes.
The answer is 15.

Answer the following question.
Jeff is collecting matchbox cars. He has twice as many cars as trucks. He has 60 total vehicles. How many trucks does he have?
Step-by-step reasoning process: The number of trucks + 2(number of trucks) = 60. Therefore 3(number of trucks) = 60. Number of trucks = 20 because 60 / 3 = 20.
The answer is 20.

Answer the following question.
Joy can read 8 pages of a book in 20 minutes. How many hours will it take her to read 120 pages?
