Question

One pipe can fill a tank in 24 minutes, a second can fill it in 8 minutes, and a third can fill it in 12 minutes. If the tank is empty, how long will the three pipes, operating together, take to fill it?

1/6 minute
4 minutes
4 4/5 minutes

Answer 1

4 min

Answer 2

Equation:
1/24 + 1/8 + 1/12 = 1/x
1/24 + 3/24 + 2/24 = 1/x
6/24 = 1/x
x(1/4) = 1
x = 4
