Swimming pool 6

We open the first pipe, and then after two hours, we open the second pipe without closing the first. The swimming pool will be filled with both pipes in 4 hours. If we open the first pipe itself, it will fill the pool 1.5 times faster than the second pipe. How many hours will each pipe take to fill the pool?

Correct answer:

a =  5.3333 h
b =  8 h

Step-by-step explanation:

4/a+2/b=1 1.5 a=b  4/a+2/(1.5 a)=1  a=4+2/1.5=5.3333 h
b=1.5 a=1.5 5.3333=8 h
