Answer this question: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?
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.
The answer is 10.

Answer this question:John gets lost on his way home. His normal trip is 150 miles and would take him 3 hours. He ends up driving 50 miles out of the way and has to get back on track. How long did the trip take if he kept the same speed?
His speed is 150 / 3 = 50 mph. He was detoured 50 * 2 = 100 miles. So that adds 100 / 50 = 2 hours. So the total trip was 3 + 2 = 5 hours.
The answer is 5.

Answer this question:There are 290 liters of oil in 24 cans. If 10 of the cans are holding 8 liters each, how much oil is each of the remaining cans holding?
10 cans are holding 8 liters each for a total of 10 * 8 = 80 liters. There are 290 - 80 = 210 litres left. There are 24 - 10 = 14 cans left. Each of the remaining cans is holding 210 / 14 = 15 liters each.
The answer is 15.

The number of Greek yogurt packs that had expired is 40 / 100 * 80 = 32. If each pack of Greek yogurt was sold at $12, for the 32 packs of greek yogurt that he returned, Bob was refunded $12 * 32 = $384.
The answer is 384.
