Water flows into a swimming pool at a rate of 9.59 gal/min. If the pool dimensions are 30.9 ft wide, 47.6 ft long and 13 ft deep, how long does it take to fill the pool? (1 gallon = 231 cubic inches). Answer in units of minutes.

Divide the pool volume (in gallons) by 9.59 gal/min
V = 19,121 ft^3 * 1 gallon/231in^3 * 1728in^3/ft^3 = 143,035 gal.
