Answer:
Rate of water filling = 540 gallons/hour
Step-by-step 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 = [tex]\frac{x\total water filled}{time taken}[/tex]
= [tex]\frac{3780}{7}[/tex]
= 540 gallons/hour
Rate of water filling = 540 gallons/hour
