It took 3 hoses 4 hours to fill the first 20,000 gallons in a swimming pool. Then a 4th hose was
added. If there was 15000 gallon left to fill, how long did it take?

assuming all the hoses have the same fill rate,
3 hoses fill 5000gal/hr, so that is 5000/3 gal/hr per hose.
now you know the hose fill rate, so multiply that by 4, and divide it into 15000gal.
