Question: Carol fills up her gas tank as she is driving home for college, which is 220 miles away. She can get 20 miles to the gallon in her car, which has a 16-gallon gas tank. How many more miles will she be able to drive after she gets home and without filling her tank again?
Answer: Step-by-step reasoning process: Divide the remaining miles of the trip by the miles per gallon her car gets. 220 miles / 20 miles / gallon = 11 gallons. Subtract the gallons used for the trip from the size of her gas tank. 16 gallons - 11 gallons = 5 gallons. Multiply the remaining number of gallons by the car's gas mileage. 5 gallons x 20 miles / gallon = 100 miles.
So the answer is 100.

Question: Alex has not washed his clothes for a month; 18 shirts, 12 pants, 17 sweaters, and 13 jeans are waiting to be washed. Alex's washing machine can wash a maximum of 15 items per cycle. Each cycle takes 45 minutes. How many hours will it take the washing machine to wash all the clothes?
Answer: Step-by-step reasoning process: Alex will wash 18 + 12 + 17 + 13 = 60 items. With 20 items per wash cycle, Alex will wash the clothes in 60 / 15 = 4 cycles. With 45 minutes per cycle, the washing machine will take 45 * 4 = 180 minutes to wash the clothes. As 1 hour has 60 minutes, the washing machine will take 180 / 60 = 3 hours to wash the clothes.
So the answer is 3.

Question: William left Missouri by 7:00 AM and arrived at his hometown by 8:00 PM. He had 3 stops of 25, 10 and 25 minutes respectively during the journey. How many hours did he spend on the road?
Answer: Step-by-step reasoning process: 8:00 PM is equivalent to 20:00 hrs so he spent a total of 20 - 7 = 13 hours on the journey. He spent 25 + 10 + 25 = 60 minutes on stops. There are 60 minutes in an hour so he spent (60 / 60) = 1 hour on stops. Therefore, he spent 13 - 1 = 12 hours on the road.
So the answer is 12.

Question: Winston has 14 quarters. He then spends half a dollar on candy. How many cents does he have left?
Answer:
Step-by-step reasoning process: Winston has 350 cents because 14 x 25 = 350. He spends 50 cents because $1 / 2 = 50 cents. He has 300 cents left at the end.
So the answer is 300.
