Water is flowing out of an artesian spring at a rate of 8 cubic feet per minute. There are 7.5 gallons of water per cubic foot. How many minutes will it take for the water to fill up a 300 gallon tank?

As the water is flowing out of the artesian spring at a rate of #8# cubic feet per minute and each cubic foot has #7.5# Gallone

the water is flowing out of the artesian spring at a rate of #8xx7.5=60# gallons per minute.

As the tank can fill up #300# gallon,

it should take #300/60=5# minutes to fill tank.
