Question: The swimming club went to a swim meet in another town. They took 2 cars and 3 vans. There were 5 people in each car and 3 people in each van. Each car can hold a maximum of 6 people and each van can hold a maximum of 8 people. How many more people could have ridden with the swim team?
Answer: The available number of people in each car is 6 * 2 cars = 12 people. The available number of people in each van is 8 * 3 vans = 24 people. The total number of people that could go with the team is 12 people + 24 people = 36 people. The team took with them 2 cars * 5 people = 10 people. The team also took 3 vans * 3 people = 9 people. The team brought 10 people + 9 people = 19 people. The team could bring an additional 36 people - 19 people = 17 people. The answer is 17.

Question: At the end of the first quarter, the winning team had double the points of the losing team. At the end of the second quarter, the winning team had 10 more points than it started with. At the end of the third quarter, the winning team had 20 more points than the number it had in the second quarter. If the total points the winning team scored in the game was 80, and the losing team had 10 points in the first quarter, calculate the total number of points the team scored in the fourth quarter.
Answer: At the end of the first quarter, the winning team had double the points of the losing team, meaning the winning team had already scored 10 * 2 = 20 points. At the end of the second quarter, the winning team had 10 more points than it started with, a total of 20 + 10 = 30 points. At the end of the third quarter, the winning team had 20 more points than the number it had in the second quarter, a total of 20 + 30 = 50 points. If the total points the winning team scored in the game was 80, they scored 80 - 50 = 30 points in the fourth quarter. The answer is 30.

Question: Tom swims for 2 hours at a speed of 2 miles per hour. He then runs for half the time at 4 times the speed. How many miles did he cover?
Answer:
He swam 2 * 2 = 4 miles. He ran for 2 / 2 = 1 hour. His running speed was 2 * 4 = 8 mph. So he ran 8 * 1 = 8 miles. So his total distance was 8 + 4 = 12 miles. The answer is 12.
