Question

Between 9 AM and 6:10 AM the water level in a swimming pool decreased by 5/12 inches assuming that the water level decreased at a constant rate how much did the water level drop each hour?

Answer 1

The water level drops each hour by 0.1472 inches/hour.

Explanation:

We are given that Between 9 AM and 6:10 AM the water level in a swimming pool decreased by 5/12 inches assuming that the water level decreased at a constant rate.

Firstly, we will find the number of hours between 6:10 AM and 9 AM, that is;

Number of hours = From 6:10 AM and 9 AM, there are 2 hours and 50 minutes

So, Number of hours =
`2 + (50)/(60)` = 2.833 hours

Also, the water level in a swimming pool decreased by =
`(5)/(12)` = 0.417 inches

Now, to find how much did the water level drop each hour, we will divide the amount of water level in a swimming pool decreased by the time interval given, that is;

=
`(0.417)/(2.833)`

= 0.1472 inches/hour.

This means that the water level drops each hour by 0.1472 inches/hour.
