how long does the whole operation tak?

Pipe A fills a 5l tank at a rate of 15l per hour. Pipe B fills the same thank at a rate of 10 l/h. Pipe A runs alone for 100 minutes then the two of them together finish filling up the tank. How long does the whole operation take?

Nenalyn, do you mean the tank is 5 litters? I did some calculations on this and if Pipe A fills the tank at a rate of 15 l/hr, then it would only take 1/3 hr or 20 minutes to fill the tank Hence, the tanks would be full long before 100 minutes.

Excuse my spelling where in some places I put 'litters' where the correct spelling is liters.
