are currently 15 gallons of water in the pool. You are filling the pool with
water at a rate of 8 gallons per minute. How many minutes until the pool is
full?

Answer 1

Answer:

11.25 minutes

Step-by-step explanation:

The capacity of the swimming pool is 105 gallons of water.

There are currently 15 gallons of water

∴I need to fill (105-15) = 90 gallons of water

Now,

8 gallons of water are filled within 1 minute

∴1 gallon of water  will be filled within = 1/8 minute

∴90 gallons of water  will be filled within = 90/8 minutes

                                                                     =11.25 minutes
