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 through a hose with .75 inch diameter!! PLease show work!! THANK YOU

Let A = amount of water, D = diameter , T = time
From ''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.''
We can get 
|dw:1333421165344:dw|
Put A1 = 500, D1 = 1 , T1 = 3 , T2 =4, D2 = 0.75 into the equation, Can you find A2?
