Volume = Gallons/Minute x Minutes ==> V = Rt V = 20a = 30b = 40c Express a and b in terms of c: a = 2c b = 4c/3 With all pipes open, the fill rate becomes: R = a+b-c R = 2c+4c/3-c R = 7c/3 Time required is Volume / Fill Rate: t = V/R t = 40c/(7c/3) t = 120/7 t = 17.14 minutes

How long will it take a tank to be be filled by one pipe in 9 minutes and drained by another pipe in 12 minutes?
We're guessing that the question is trying to ask:If one pipe can fill the tank in 9 minutes, and another pipecan empty the tank in 12 minutes, how long does it take thetank to fill if both pipes are open ?So that's the question we'll go ahead and answer.The first pipe fills 1/9th of the tank every minute.The second pipe empties 1/12th of the tank every minute.When they're both open, (1/9 - 1/12) of the tank fills every minute.(1/9) - (1/12) = (4/36) - (3/36) = 1/36Since 1/36th of the tank fills every minute, it takes 36 minutes to fill.
