Answer 1

Rate of water filling = 540 gallons/hour

Explanation:

Joe's pool has 1500 gallons of water in it from last summer.

After filling the pool for 7 hours, there are 5280 gallons of water in it.

The additional amount of water filled in the pool = final - initial = 5280 - 1500 = 3780 gallons

So 3780 gallon of water is filled in the tank in 7 hours.

The rate of filling of water =
`(x\total water filled)/(time taken)`

=
`(3780)/(7)`

= 540 gallons/hour

Rate of water filling = 540 gallons/hour
