You can put this solution on YOUR website! Inlet ‘1’ and ‘2’ together can fill a tank in 18 hours. Inlet ‘2’ can fill the tank on its own in 24 hours. In how many hours can inlet ‘1’ alone fill the tank?
.
Let x = time (hours) for inlet 1 alone
then
18(1/x + 1/24) = 1
multiplying both sides by 24x:
18(24 + x) = 24x
432 + 18x = 24x
432 = 6x
72 hours = x
