Respuesta :

Explanation

We are asked to find the change in the water level per hour for Patrick's swimming

We have to use the formula

[tex]change\text{ in water level per hour=}\frac{Volume\text{ of water}}{Time\text{ taken to drain}}[/tex]

Thus

[tex]change\text{ in water level per hour=}\frac{9644.6}{8}=1205.575\text{ gallons per hour}[/tex]

Note: The rate will be negative because we are draining

Therefore, the change in water level will be -1205.58 gallons per hour
