[Question]For homework, Brooke has 15 math problems, 6 social studies problems, and 10 science problems. He can answer each math problem for 2 minutes while answering each social studies problem takes him 30 seconds. If he can answer each science problem in 1.5 minutes, how long will it take Brooke to answer all his homework?
[Answer]Brooke will take 15 x 2 = 30 minutes to answer all math problems. It will take him 6 x 30 seconds = 180 seconds to answer all social studies problems. In minutes, this is equal to 180 / 60 = 3 minutes. It will take him 10 x 1.5 minutes = 15 minutes to answer all science problems. Therefore, Brooke will take 30 + 3 + 15 = 48 minutes to finish his homework. The answer is 48.

Question: Timmy's parents have a 2 car garage, which has both cars inside it. Also inside is a riding lawnmower, a bicycle for Timmy as well as each of his parents, a tricycle for Timmy's little brother Joey, and a unicycle that Timmy's dad practices riding on.

Each car in the garage has 4 wheels, for a total of 4 * 2 = 8 wheels. The riding lawnmower has 4 wheels, bringing the total up to 8 + 4 = 12 wheels. The bicycles have 2 wheels each and there are 3 of them, for 3 * 2 = 6 wheels, bringing the total to 12 + 6 = 18. The tricycle has 3 wheels, and the unicycle has 1 wheel, bringing the total up to 18 + 1 + 3 = 22 wheels. The answer is 22.
