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 set up a proportion based on the information given.

3 cans / (2/3) minutes = x cans / 1 minute

Now we can solve for x by multiplying both sides by 3/2.

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

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

The answer is C. 4 1/2.
