Between 9 PM and 6:36 AM, the water level in a swimming pool decreased by 4/25 Assuming that the water level decreased at a constant rate, how much did the water level drop each hour? pls help

per hour

Step-by-step explanation:

First, you need to find the total amount of time that the pool decreased by 4/25. Since there are 9 hours and 36 minutes between 9 PM and 6:36 AM, this time is 9 hours and 36 minutes. Next, convert this time into hours, which gives the time as 6 and 36/60 hours, or 9 hours.

For this problem you need to find the rate at which the water decreases. To do this you can use the equation . Substitute in the given change of 4/25 and time of 6.6 and you get the equation . Solving this by changing the fractions to improper fractions and doing fraction division gives .
