Pool 2

The first supply is by the pool fill for five hours and the second fill for six hours. The drain should be drained for 15 hours. How many hours is the pool full when we open both inlets now, and the outlet opens two hours later?

Correct answer:

x =  2.889 hod

Step-by-step explanation:

6x+5x15x2=1 x=26/9 h

x/6+x/5-(x-2)/15=1

9x = 26


x = 26/9 = 2.88888889

x = 26/9 ≈ 2.888889
