SOLUTION: The amount of water pumped through a hose varies directly as the square of the diameter of the hose and inversely as the time the water is turned on. It takes 3 hours to pump 500 g

Question 596543: The amount of water pumped through a hose varies directly as the square of the diameter of the hose and inversely as the time the water is turned on. It takes 3 hours to pump 500 gallons of water through a hose with a 1 inch diameter. How many gallons of water (to the nearest gallon) can be pumped in 4 hours though a hose with a .75 inch diameter?
