Question

Two pools are being filled at the same time. Pool A has 35 gallons of water and its being filled at 8 gallons per hour. Pool B has 50 gallons of water and is being filled at a rate of 5 gallons an hour. How many hours will it take for pool A to be more than the water in pool B?

Answer 1

Answer: 6 hours

Step-By-Step Explanation: The difference in the rate of Pool A and Pool B is 3 gallons per hour. That means that every hour, Pool A gains 3 gallons on Pool B which means by 5 hours, the 15-gallon difference will be equal. Since the question is asking for more than not equal, it's required for 1 more hour for Pool A to be greater than pool B
