Answer:
[tex]W = \frac{1}{3}t[/tex]
20 gallons of water is leaked after an hour.
Step-by-step explanation:
Water is leaking at a constant rate of 1/3 gallon per minute.
a) We have to write a linear equation in two variables that show the amount of water, w, in gallons, that is leaked from the faucet after t minutes.
So, the equation is [tex]W = \frac{1}{3}t[/tex] ......... (1) (Answer)
b) Now, if t = 1 hour i.e. 60 minutes, then from equation (1) we can write
[tex]W = \frac{1}{3}\times 60 = 20[/tex] gallons.
Therefore, 20 gallons of water is leaked after an hour. (Answer)
