The table below shows how the number of hours needed to fill a pool depends on the flow rate of the hoses used to fill it.
Flow rate, x
(gal/hr)
Time, y
(hours)
60gal = 300hrs
45gal =400 hrs
36 gal = 500 hrs
30 gal = 600 hrs
How long will it take to fill the pool if two hoses are used, one that fills at a rate of 40 gallons per hour and one that fills at a rate of 60 gallons per hour?
100 hours
150 hours
180 hours
200 hours

Best ResponseYou've already chosen the best response.0The table is confusing. Are the 60, 45, 36, and 30 flow rates or are they the amount of gallons the hose puts out in the given times?

Best ResponseYou've already chosen the best response.0Do you guys think it could be 150?

Best ResponseYou've already chosen the best response.0ok. I think I get it. If you multiply all the flow rates by the time you get the size of the pool as 18000 gallons

Best ResponseYou've already chosen the best response.0Per @Skielerlucas04 the two hoses have a combined flow rate of 100 gal/hr. So t = 18000/100 = 180 hr
