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

    The 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?

    The unit says gallons but the heading says gal/hr

    The 60, 45,36, 30 heading is Flow rate, x (gal/hr)

    so its the flow rate in gal/hr

    Do you guys think it could be 150?

    ok. 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

    Per @Skielerlucas04 the two hoses have a combined flow rate of 100 gal/hr. So t = 18000/100 = 180 hr
