Question

A hose fills a small swimming pool at a rate of 15 cubic feet per 60 seconds. Which equation can be used

to find the amount of cubic feet, y, in x seconds?

Answer 1

y = 1/4x

Explanation:

y = amount of cubic feet = 15 cubic feet

x = time taken = 60 seconds

y = kx

Where,

k = constant of proportionality

y = kx

15 = k * 60

k = 15/60

k = 1/4

The equation

y = kx

Where

k = 1/4

Becomes,

y = 1/4x
