Uriel collects aluminum cans, crushes them with a hand can-crushing machine, and turns the crushed cans in once a month for extra money.

Question

Uriel can crush 3 cans in 2/3 of a minute. What is the rate, in cans per minute, at which Uriel crushes aluminum cans?

A. 2/9
B. 4 1/4
C. 4 1/2
D. 2

Answer 1

To find the rate at which Uriel crushes aluminum cans, we need to divide the number of cans by the time it takes to crush them.

3 cans / (2/3) minutes = 3 cans * 3/2 minutes = 9/2 cans = 4 1/2 cans

Therefore, the rate at which Uriel crushes aluminum cans is 4 1/2 cans per minute.

The answer is C. 4 1/2
