it will take 4.9 hours to fill the pool with 3185 gallons of water.
Step-by-step explanation:
The total volume of water that the community pool holds is 3185 gallons of water. It takes 2.5 hours to fill the pool with 1625 gallons of water. Therefore, the number of hours it will take to fill the pool with one gallon would be
2.5 / 1625 = 0.00154 hours per gallon.
