Pipe A can fill a tank in 32 minutes.

Pipe A can fill a tank in 32 minutes. Pipe B can fill the same tank 5 times faster than pipe A. If both the pipes are connected to the tank so that they fill the tank simultaneously, how long will it take for the empty tank to overflow?

Answer/Solution

32/7 minutes

Steps/Work

Pipe A can fill a tank in 32 minutes --> the rate of A = 1/32 tank/minute;
Pipe B can fill the same tank5 times fasterthan pipe A --> the rate of B = 1/32 + 5/32 = 6/32 tank/minute.
Their combined rate = 1/32 + 6/32 = 7/32 tank/minute;
Therefore, A and B can fill the tank in 32/7 minutes.
