The two pools must drain for almost 30.2 minutes in order to have the same amount of water.
<h3>What is Equation Modelling?</h3>
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given are two neighbors and the rate at which their pools are draining.
Assume that it will take (m) minutes to drain both pools in order to have same level. Assume that the amount of water at the same level is (y).
Water level in Mr. Zoetrope's pool after (m) min -
y = 10858 - 150m [1]
Water level in Mrs. Horner's pool after (m) min -
y = 9650 - 110m [2]
Equating equations [1] and [2], we get -
10858 - 150m = 9650 - 110m
10858 - 9650 = 150m - 110m
40m = 1208
m = 30.2 minutes
Therefore, the two pools must drain for almost 30.2 minutes in order to have the same amount of water.
