Question and rationale: The question is: 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?
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.

Question and rationale: The question is: Bethany loved riding horses. She rode 1 hour after school every Monday, Wednesday, and Friday. On Tuesday and Thursday, she rode for 30 min and on Saturdays, she could ride for 2 hours. How many hours in total did she ride over a 2 week period?
Step-by-step reasoning process: She rode 1 hour every Monday, Wednesday and Friday each week so every week she rode 1 * 3 = 3 hours. She rode 30 min on Tuesday and Thursday each week for a total of 30 * 2 = 60 min or 1 hour. On Mon, Wed & Friday she rode 3 hours, 1 hour total on Tue and Thur and 2 hours on Sat for a total of 3 + 1 + 2 = 6 hours. She rode 6 hours per week for 2 weeks so in total she rode 6 * 2 = 12 hours.

Question and rationale:
The question is: Prejean's speed in a race was three-quarters that of Rickey. If they both took a total of 70 minutes to run the race, calculate the total number of minutes that Rickey took to finish the race.
Step-by-step reasoning process: Let's say Rickey took t minutes to finish the race. If Prejean's speed in the race was three - quarters that of Rickey, and Rickey took t minutes to finish the race, the time that Prejean took to finish the race is 3 / 4 * t = 3 / 4t. Together, Rickey and Prejean took t + 3 / 4t = 70. They took 1 3 / 4 t hours = 70 to finish the race. This is 7 / 4t = 70. t = 70 * 4 / 7. The time that Rickey took to finish the race is t = 40 minutes.
