Question

A water tank holds 18000 gallons. How long will it take for the water level to reach 6000 gallons if the water is used at an average rate of 450 gallons per day?

Answer 1

26 2/3 days

Explanation:

18000 less 6000 is 12000. How long will it take, at 450 gal/day, to drain 12000 gallons of water?

12000 gallons

------------------------- = 26 2/3 days

450 gallons/day

Answer 2

well, if it averages 450/day
and you have to find out how many days it will be to get to 6000
you have to set up an equation.

450/1 day
6000/x

is your rate equation, and to find out how many days you have to divide 6000 by 450
6000 ÷ 450 = x

in this case
x = 13.3

so it would take 13.3 days (or if you have to round it, it would take 14 days)
