Question 934306: Please help me solve this question: Pipe A can fill a tank in 5 h. Pipe B can fill it in 2 h less time than it takes Pipe C, a drainpipe, to empty the tank. With all three pipes open, it takes 3 h to fill the tank. How long would it take to pipe C to empty it?
I am still very confused, can you fully solve the problem?
