The number of pools clean per hour is 1.5

Step-by-step explanation:

Given as :

The number of pools clean in 8 hours = 12

The number of pools clean in 7.5 hours = 9

Let The number of pools they clean per hours = x

I.e x = $\frac{8}{12}$ + $\frac{7.5}{9}$

Or, x = $\frac{24+30}{36}$

Or, x = $\frac{54}{36}$

∴ x = $\frac{3}{2}$

I.e x = 1.5
