The first snake is 24 inches because there are 12 inches in a foot. The snakes are 24 + 16 + 10 = 50 inches long.
The answer: 50
Reverse engineering the question: Christina has 3 snakes. 1 snake is 2 feet long. Another snake is 16 inches long. The last snake is 10 inches long. How many inches are all of her snakes combined?


Reasoning and answer: It took Leo 25 x 2 = 50 minutes to finish the second part of the assignment. Leo finished the first and second parts of the assignment in 25 + 50 = 75 minutes. He finished the entire assignment in 60 x 2 = 120 minutes. Therefore, it took Leo 120 - 75 = 45 minutes to finish the third part of the assignment.
The answer: 45
What was the question?
Question: Leo's assignment was divided into three parts. He finished the first part of his assignment in 25 minutes. It took him twice as long to finish the second part. If he was able to finish his assignment in 2 hours, how many minutes did Leo finish the third part of the assignment?


He got 2 * 6 = 12 hours the first 2 days. The next 2 days he gets 2 * 10 = 20 hours. So he got 12 + 20 = 32 hours.
The answer: 32
Reverse engineering the question: Tim gets 6 hours of sleep 2 days in a row. To make up for it he sleeps 10 hours the next 2 days. How much sleep did he get?


Reasoning and answer: Whitney is buying 2 posters for $5 each, so the posters will cost 2 * $5 = $10 total cost for posters. Whitney is buying 3 notebooks for $4 each, so the notebooks will cost 3 * $4 = $12 total cost for notebooks. Whitney is buying 2 notebooks for $2, so the bookmarks 2 * $2 = $4 total cost for bookmarks. Since Whitney is paying $10 for posters, $12 for notebooks, and $4 for bookmarks, her total purchase will cost $10 + $12 + $4 = $26 total purchase cost. Whitney’s mom gave her 2 $20 bills, so she will be paying with 2 * $20 = $40 total payment. Since Whitney is paying with $40 and her purchase cost will be $26, she will have $40 - $26 = $14 left over after the purchase.
The answer: 14
What was the question?
Question: Whitney’s mom gave her two $20 bills to spend at the school book fair. Whitney has decided to buy 2 posters, 3 notebooks, and 2 bookmarks. Each poster costs $5, each notebook costs $4, and each bookmark costs $2. How much money, in dollars, will Whitney have left over after the purchase?


Originally, the houses are 7300 + 5200 = 12500 sq. ft. in total. The smaller house will be expanded by 16000 - 12500 = 3500 sq. ft.
The answer: 3500
Reverse engineering the question: There is a 5,200 sq. ft. house and a 7,300 sq. ft. house next to each other. The smaller house is being expanded. If the new total square footage of both houses is 16,000 sq. ft., how much is the smaller house being expanded by, in sq. ft.?


He bikes 20 * 2 = 40 miles each day for work. So he bikes 40 * 5 = 200 miles for work. That means he bikes a total of 200 + 200 = 400 miles for work. So he bikes a total of 400 / 25 = 16 hours.
The answer: 16
Reverse engineering the question:
Tim rides his bike back and forth to work for each of his 5 workdays. His work is 20 miles away. He also goes for a weekend bike ride of 200 miles.  If he can bike at 25 mph how much time does he spend biking a week?
