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.
