Gentry assembled a new 24 foot round pool in her backyard. To fill the pool with water, she used four hoses. Two of the hoses each deliver water at a rate of 2 gallons per minute. The other two hoses each deliver water at a rate of 3 gallons per minute. With a volume of 15,000 gallons, how many hours will it take to fill the pool?
Let's be accurate as possible. Think before you answer.

Each of the two hoses delivers water at a rate of 2 gallons per minute, for a combined total of 2 * 2 = 4 gallons of water per minute.

The other two hoses each deliver water at a rate of 3 gallons per minute, for a combined total of 2 * 3 = 6 gallons of water per minute.

Thus, all four hoses deliver a combined total of 4 + 6 = 10 gallons of water per minute.

With a volume of 15,000 gallons, it would take 15,000 / 10 = 1500 minutes to fill the pool.

Converting to hours, it will take 1500 / 60 = 25 hours to fill the pool.

So, the final answer is 25
