Question

Patrick has a swimming pool that needs to be drained. His pool holds9,644.6 gallons of water and will need to drain completely in 8 hours.What is the change in the water level per hour for Patrick's swimmingpool? Round your answer to the nearest hundredth.

Answer 1

Step-by-step explanation

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

We have to use the formula

`change\text{ in water level per hour=}\frac{Volume\text{ of water}}{Time\text{ taken to drain}}`

Thus

`change\text{ in water level per hour=}(9644.6)/(8)=1205.575\text{ gallons per hour}`

Note: The rate will be negative because we are draining

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