If there are 2 / 5 times as many books as the number of tables in the class on top of each table, there are 2 / 5 * 500 = 200 books. Since the class has 500 tables with 200 books on top of each, there are 500 * 200 = 100000 books.
The answer: 100000

Reasoning and answer: The friend drives 40 * 3 = 120 miles. Thus, Christina drives 210 - 120 = 90 miles. Since the speed limit is 30 miles per hour when Christina is driving, she drives for 90 / 30 = 3 hours. Thus, she drives for 3 * 60 = 180 minutes.
The answer: 180

Reasoning and answer: The birds' flying distance between Lake Jim through lake Disney to lake London is 50 + 60 = 110 miles. Since each bird flies the 110 miles distance while migrating, the combined distance they fly together is 110 * 20 = 2200 miles.
The answer: 2200
What was the question?
Question: 20 birds migrate on a seasonal basis from one lake to another, searching for food. If they fly from lake Jim to lake Disney in one season, which is 50 miles apart, then the next season they fly from lake Disney to lake London, 60 miles apart, calculate the combined distance all of the birds have traveled in the two seasons.


Reasoning and answer: For 1 match won, Joe's team scored 1 * 3 = 3 points. For 3 tied games, Joe's team scored 3 * 1 = 3 points. In total, Joe's team scored 3 + 3 = 6 points. For 2 games won, the first - place team scored 2 * 3 = 6 points. For 2 tied games, the first - place team scored 2 * 1 = 2 points. In total, the first - place team scored 6 + 2 = 8 points. The first - place team outscored Joe's team by 8 - 6 = 2 points.
The answer: 2
