Filling the Family Pool
Volume and Rate
How long will it take to fill your pool?
The Smith family just installed a new pool. The pool is 18.5 ft. wide, 36.5 feet long. The depth of the pool on the shallow end is 3 feet and 8 feet in the deep end. Water comes out of a hose at a rate of 9 gallons per minute. How many hours will it take to fill the pool?
How much will it cost to fill the pool?
The Smith's filled their new pool, but want to anticipate what their water bill will be after filling this pool. The average cost of water is $4.80 per 1,000 gallons, so how much will the pool filling add to their water bill?
