A water pump fills a dolphin tank at the aquarium at the rate of 100 gallons per minute. The tank holds 75,000 gallons of water when its full. Which calculation should be used to determined how many hours the water pump will take to fill the tank?

A. (75,000 · 100)·60

B. (75,000 · 100) ÷ 60

C. (75,000 ÷ 100) · 60

D.(75,000 ÷ 100) ÷ 60

It is C.

Explanation:

You would need to divide 75,000 by 100 to get how many minutes it would take to get to 75,000. You get 750 and after that, multiply it by 60 because there is 60 minutes in an hour.
