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

Keywords:

Tank, capacity, water, gallons, rule of three, variable, days

For this case we have a tank with a capacity of 18,000 gallons, we want to know how many days 12000 gallons of the tank are emptied, with the use of water following an average rate of 450 gallons per day. So we make a rule of three according to the use of water per day:

450 gallons -----------> 1 day

12000 gallons -------> x

Where the variable "x" represents the number of days when water takes to reach 6000 gallons.

$x = \frac {12000 * 1} {450}\\x = 26.67$

Rounding the nearest whole we have:

$x = 27$

Answer:

For the tank to go from 18,000 gallons of water to 6000 gallons of water, it should take approximately 27 days, using the water at an average rate of 450 gallons per day.

$x = 27\ days$

Answer 2

D = days   18000-450d=6000 It would take 26 days
