A pool is being drained at a rate of 120 gallons per minute. What is this rate in quarts per hour?

So,
120 gal./min.
There are 4 qt. in a gal.
Multiply 120 by 4. 120(4) = 480 qt.
The pool is being drained at a rate of 480 qt./min.
Now, since there are 60 min. in an hr., multiply 480 by 60. 480(60) = 28,800 qt./hr.
The pool is being drained at a rate of 28,800 qt./hr. (quarts per hour)

The pool is draining at a rate of 28,800 quarts per hour, which is found by converting 120 gallons per minute to quarts and then adjusting for an hour. The conversion steps involve multiplying by the number of quarts per gallon and then by the number of minutes in an hour.
