Answer:

1 1/2 hours.

Step-by-step explanation:

We work in fractions of the pool that the hoses can fill in 1 hour, and this gives us the equation:

1/4 + 1/6 + 1/8 + 1/8 = 1/x    where x is the times taken by 4 hoses turned on.

LCD  = 24x so, multiplying through by 24x, we get:

6x + 4x + 3x + 3x = 24

16x = 24

x = 1 1/2 hours.
