if the supply pump can pump p gal/min,
and the outlet pumps each draw q gal/min,
30(p-q) = 8450
45(p-2q) = 10950
(p,q) = (320,115/3)
Now you can convert that to gal/hr.
A fuel storage tank has one supply pump and two identical outlet pumps. With one outlet pump running, the supply pump can increase the fuel level in the storage tank by 8450 gallons in 30 minutes. With both outlet pumps running, the supply pump can increase the fuel level in the storage tank by 10,950 gallons in 45 minutes. Find the pumping rate, in gallons per hour, for each of the pumps.
supply pump gal/h
each outlet pump gal/h
