HELP PL! I WILL GIVE YOU BRAINLIEST PLS HELP! Between 11 P. M. and 8:20 A. M., the water level in a swimming pool decreased by 4/15 inches. Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?

Step-by-step explanation:

Divide the decrease in water level by the length of the time interval.

decrease = 7/12 inches ≅ 0.583 inches

Time interval: From 11 pm to 8:20 am you have 9:20 hours = (9 + 20/60) hours ≅ 9.33 hours  

So the water drops at a rate of about

0.583/9.33 inches/hour ≅ 0.0625 inches/hour

That means that each hour it drops about 0.0625 inches
