Every second month Nina does twice the regular distance, which means 400 * 2 = 800 kilometers. Two years is 24 months, so half of this time is 24 * 0.5 = 12 months. So in 12 months Nina does 400 * 12 = 4800 kilometers. And in the other 12 months, she does 800 * 12 = 9600 kilometers. So in two years, Nina would be able to make 4800 + 9600 = 14400 kilometers.
The answer: 14400
Reverse engineering the question: Nina loves to travel. She tries to travel at least 400 kilometers in one month outside of her home country. Every second month she does twice that distance. If she were able to keep up with her resolution, how many kilometers would she travel during 2 years?
Reasoning and answer: If the first 100 miles took one hour, then let's say the next 300 miles took x hours. if 100 miles = 1 hour, then 300 miles = x. To find the number of hours traveled for the 300 miles, x = 300 * 1 / 100. x = 3 hours. The total number of hours will be 3 + 1 = 4 hours.
The answer: 4

Question: Emery's family decides to travel for a weekend trip. They drive the first 100 miles in 1 hour. They stop at a McDonald's and then continue the rest of the journey for 300 miles. What's the total number of hours they traveled?
If Adelaide bought 30 ducks, Ephraim bought 30 ducks / 2 = 15 ducks. Since Ephraim bought 45 fewer ducks than Kolton, Kolton bought 45 ducks + 15 ducks = 60 ducks. The total number of ducks the three bought is 60 ducks + 15 ducks + 30 ducks = 105 ducks. The average number of ducks each bought is 105 ducks / 3 people = 35 ducks / person.
The answer: 35
Reverse engineering the question: A teacher asked Adelaide, Ephraim, and Kolton to buy ducks and monitor their growth patterns and features for their science class. Adelaide bought twice the number of ducks that Ephraim bought, while Ephraim bought 45 fewer ducks than Kolton. If Adelaide bought 30 ducks, what's the average number of ducks the three bought?
Reasoning and answer: The team is 40% girls because 100 - 60 = 40. The team has 20 girls because 50 x .4 = 20. The team has 10 junior girls because 20 / 2 = 10.
The answer: 10

Question: Ben's hockey team is 60% boys and the rest are girls. Half the girls are juniors and the other half are seniors. If the team has 50 players, how many junior girls are there?
If the first page had 5 drawings, and the number of drawings on each page increased by five, the second page had 5 + 5 = 10. The total number of drawings in the first 2 pages is 5 + 10 = 15. On the third page, the number of drawings increased to 10 + 5 = 15. The first three pages have a total of 15 + 15 = 30 drawings. The fourth page had 15 + 5 = 20 drawings. There are 30 + 20 = 50 drawings on the first four pages. The fifth page also had an extra 5 more drawings than the fourth page, totaling 20 + 5 = 25. For the first five pages, Janice saw 25 + 50 = 75 pages.
The answer: 75
Reverse engineering the question: Janice opened an art book that she had found in the library and found 5 drawings on the first page. After opening the first ten pages, she realized that the number of drawings on each page increased by five after every page. How many drawings were in the first five pages?
Wally gives his friends 3 / 4 * 400 = 300 tickets to share. The total ratio that represents the tickets that Jensen and Finley share is 4 + 11 = 15. From the total ratio, the fraction that represents the share that Finley got is 11 / 15, and since he shared with Jensen 300 tickets, he got 11 / 15 * 300 = 220 tickets.
The answer: 220
Reverse engineering the question:
Wally gives 3/4 of his 400 tickets to his two friends Jensen and Finley, who share the tickets in a ratio of 4:11. How many tickets does Finley get?
