The sewers in Middleton can handle 240,000 gallons of run-off. Each hour of rain produces 1000 gallons of runoff. How many days of rain can the sewers handle before they overflow? Think carefully first, then make a decision:
First find how many hours of runoff the sewers can handle: 240,000 / 1000 gallons / hour = 240 hours. Then divide that time by the number of hours per day to find how many days of rain the sewers can handle: 240 hours / 24 hours / day = 10 days. So, the answer is 10.
