Question

A pipe is leaking in the school bathroom. It has leaked 3 gallons of water in 6 hours.
COP=

Answer 1

COP [Constant of Proportionality or k] = ½

Explanation:

y = kx.

y = dependent variable [vertical].

x = independent variable [horizontal].

y in this case is the gallons and x in this case is the hours.

Therefore

#gallons = 1/2 #hours

y = 1/2x

k = 1/2

____________

This is because at a rate,

the pipe leaks at 1/2 or 0.5 gallons per hour.
