Problema Solution
If you have a room that is 12.5 feet long by 11 feet wide by 8.5 feet tall, how long would it take you to fill the room using two hoses, one that delivers 9.5 gallons per minute and the other that delivers 11 gallons per minute?
Answer provided by our tutors
volume of the room:
12.5*11*8.5 = 1168.75 ft^3
total flow of water into the room:
9.5+11 = 20.5 gallons per minute
we want to convert from ft^3 to gallons and we use
1 ft^3 = 7.48 gallons
time to fill:
(1168.75/7.48)/20.5 = 7.62
it would take approximately 7.62 minutes
