Reverse engineering the question: Every day, while going to school, Shane drives a total of 10 miles. Calculate the total distance he drives in an 80 day semester from home to school and back.


Reasoning and answer: When Jennifer is 30 years old in ten years, her sister Jordana will be 3 * 30 = 90 years old. She's currently 10 years younger, so she's 90 - 10 = 80 years old.
The answer: 80
What was the question?
Question: Jennifer will be 30 years old in ten years. At that time, her sister Jordana will be three times as old Jennifer. How old is Jennifer's sister now?


Bowen bought 2 / 5 * 40 pens = 16 more pencils than pens. The total number of pencils that he bought is 40 pencils + 16 pencils = 56 pencils. If each pencil costs twenty - five cents, the total amount of money he spent on pencils is 56 pencils * $0.25 / pencil = $14. On pens, Bowen spent $0.15 / pen * 40 pens = $6. The total amount of money Bowen spent is $14 + $6 = $20.
The answer: 20
Reverse engineering the question: At A.T. Cross Luxury Pens, a pencil sells at twenty-five cents while a pen sells at fifteen cents. Bowen buys 40 pens and 2/5 times more pencils than pens from A.T. Cross Luxury Pens. Calculate the total amount of money Bowen spends.


Reasoning and answer: His first drive was 30 * .5 = 15 miles. The next leg was .5 * 2 = 1 hour. The speed of the trip was 30 * 2 = 60 mph. So he drove 60 * 1 = 60 miles. So in total he drove 60 + 15 = 75 miles.
The answer: 75

Question: James drives 30 mph for half an hour and then twice as long for twice the speed. How far did he drive in total?


If each user posts an average of 3 questions per hour, the average number of answers posted on the forum is 3 times the number of questions which totals to 3 * 3 = 9 answers per. hour. In a day, with 24 hours, the average number of questions asked by each member is 24 * 3 = 72,. If there are 200 users of the forum, the total number of questions asked is 200 * 72 = 14400 questions in a day. At the same time, a member posts an average of 9 * 24 = 216 answers in a day. Since there are 200 members who use the forum, the total number of answers posted in the forum in a day is 200 * 216 = 43200. In total, the number of questions and answers posted on the forum is 43200 + 14400 = 57600.
The answer: 57600
Reverse engineering the question: A question and answer forum has 200 members. The average number of answers posted by each member on the forum is three times as many as the number of questions asked. If each user posts an average of 3 questions per hour, calculate the total number of questions and answers posted on the forum by its users in a day.


Monika spent 24 * 3 = 72 dollars at the movies. Monika spent 20 * 1.25 = 25 dollars at the farmers market. Throughout her day, Monika spent 250 + 72 + 25 = 347 dollars.
