Eric is adding water to a 60-gallon pool.

The pool already has 12 gallons of water, and he wants to fill it to at least 27 gallons. The water flows at a rate of 6 gallons per minute.

How many minutes, x, will it take for Eric to fill the pool with at least 27 gallons of water?

He is filling it at a rate of 6 gallon per minute

suppose it takes x minutes to reach 27 gallon

water filled in x minutes =

water already present + volume of water at the rate of 6 in x minutes

12 gallons + 6 gallon. minute 8 x minutes

12 + 6x

This should be equal to atleast 27

12 + 6x = 27

let us subtract 12 from both sides

6x = 27-12

6x = 15

divide both sides by 6

x = 2.5

Answer

It will take 2.5 minutes to reach 27 gallon.

When He start to fill the water
