Question: There are 3 kids waiting for the swings and twice as many kids waiting for the slide. If each kid waits 2 minutes for the swings and 15 seconds for the slide, how many seconds shorter is the shorter wait?
Answer: First find the total wait time for the swings in minutes: 3 kids * 2 minutes / kid = 6 minutes. Then convert that number to seconds: 6 minutes * 60 seconds / minute = 360 seconds. Then find the total number of kids waiting for the slide: 3 kids * 2 = 6 kids. Then find the total wait time for the slide: 15 seconds / kid * 6 kids = 90 seconds. Then subtract the total wait for the slide from the total wait for the swings to find the difference: 360 seconds - 90 seconds = 270 seconds. The answer is 270.
[Question]Jamie is in a walking group with 4 other ladies. The ladies all walk 3 miles together. On top of that, Jamie walks an additional 2 miles per day for 6 days while her friend Sue walks half that amount in 6 days. If they walk this same route 6 days a week, how many miles do the ladies walk in total?
[Answer]There are 5 ladies total in the group. They all walk 3 miles a day for 6 days so 3 * 6 = 18 miles. Jamie walks an additional 2 miles per day for 6 days so 2 * 6 = 12 miles. Sue walks half the distance of Jamie so 12 / 2 = 6 miles. Together, the ladies walk 18 + 12 + 6 = 36 miles. The answer is 36.

[Question]There are 400 students. 120 students take dance as their elective. 200 students take art as their elective. The rest take music. What percentage of students take music?
