A pool is being drained at a rate of 120 gallons per minute what is the rate in quarts per hour

288 quarts per hour.

Step-by-step explanation:

So ... 120 x 60 = 7200 gallons per hours, because 60 minutes equal and hour and it is asking how many "quarts" is getting drained per hour. Then you take 7200 and divide it by 25 because when you divide 0.25 (since that is a quart in a gallon) you have to put 0.25 as 25 and then when you divide 7200/25 you get 288 quarts per hour.

120 gallons = 480 quarts.

480 quarts x 60 minutes = 28,280

It is being drained at 28,280 quarts per hour.
