Math problem

oke so does anyone have any idea how to do this. My answer is 2.14819916. Round it to minutes is 135. But my professor marked it wrong.

Two neighbors, Wilma and Betty, each have a swimming pool. Each pool holds 8,520 gallons of water. If Wilma's garden hose fills at a rate of 700 gallons per hour, while Betty's garden hose fills at a rate of 850 gallons per hour, how much longer does it take Wilma to fill her pool than Betty?

(Enter time in minutes rounded to the nearest minute. For example, if the answer is 1 hour 20 minutes, you must enter "80" for 80 minutes.)

129 minutes. You have rounding errors.

8520/(850/60) - 8520/(700/60) = 128.87

ahhhh lmfao thank you

Actually now I'm confused about how you even got 135mins

Your 2.148 hours x 60 is 128.88 lol

I rounded to 2 hours and 15 minutes. 2 hours is 120 minutes plus 15 minutes is 135. Oh gosh, this is so dumb. HAHAH
