Question

pipe a can fill a tank in 5 hours and pipe B can empty it in 5 hours if both the pipes are open at the same time when will the tank be full​

Answer 1

Answer:

X=2 8/11 hrs

Step-by-step explanation:

Let x be the time when the tank is full.

As both the pipes are opened at one time

x/5 + x/6 = 60

(6x + 5x) / 30 = 60

11x = 1800 / 60 min

11x = 30 hrs

x = 30 / 11 or 2 8/11 hrs
