A girl collects aluminum cans crushes them with a hand can crushing machine then turns the crushed cans in once a month for extra money
She can crush three cans in 2/3 of a minute what is the rate in cans per minute at which The girl crushes aluminum cans
To find the rate at which the girl crushes aluminum cans per minute, we need to calculate how many cans she can crush in one minute.
If the girl can crush 3 cans in 2/3 of a minute, then we can convert this to a rate in cans per minute by setting up a proportion:
3 cans / (2/3) minute = x cans / 1 minute
Now we can solve for x:
3 / (2/3) = x
3 * (3/2) = x
9/2 = x
Therefore, the girl crushes aluminum cans at a rate of 4.5 cans per minute.
