[Question]James is trying to decide which trail is faster to hike. One trail is 20 miles and mostly downhill, so James can cover it at 5 miles per hour. The other trail is 12 miles, but it's mostly uphill, so James will only be able to cover 3 miles per hour and will have to take an hour break halfway through. How many hours faster is the fastest hike?
[Answer]First find how long the first trail takes to hike: 20 miles / 5 miles / hour = 4 hours. Then find how long James spends hiking the second trail: 12 miles / 3 miles / hour = 4 hours. Then add the 1 hour break James has to take on the second trail: 4 hours + 1 hour = 5 hours. Then subtract the time for the first trail from the time for the second trail to find the difference: 5 hours - 4 hours = 1 hour. The answer is 1.
Q: Four adults with 32 teeth went to the dentist for a checkup after realizing they were having severe tooth pain. They were found to have different numbers of damaged teeth, and each person had some teeth removed. The first person had 1/4 of all his teeth removed, and the second person had 3/8 of his teeth removed, the third person had half of his teeth removed, while the last person only had 4 teeth removed. What's the total number of teeth removed at the dental clinic?
A: The first person had 1 / 4 of all his teeth removed, a total of 1 / 4 * 32 = 8 teeth. The second person had 3 / 8 of his teeth removed, meaning 3 / 8 * 32 = 12 of his teeth were removed. Together, the first and the second person had 12 + 8 = 20 teeth removed in total. The third person had half of his teeth removed, which were 1 / 2 * 32 = 16 teeth. The first three people had a total of 20 + 16 = 36 teeth removed from their mouth. The last person only had 4 teeth removed, bringing the total number of teeth removed at the dentist clinic to be 36 + 4 = 40 teeth. The answer is 40.
Question: John buys 3 puzzles. The first puzzle has 1000 pieces. The second and third puzzles have the same number of pieces and each has 50% more pieces. How many total pieces are all the puzzles?
Answer: The second puzzle has 1000 * .5 = 500 more pieces than the first. So it has 1000 + 500 = 1500 total pieces. That means those two puzzles have 1500 * 2 = 3000 pieces. So in total there were 3000 + 1000 = 4000 pieces. The answer is 4000.
[Question]Polly the parakeet tweets all day long. When she is happy, she tweets 18 times per minute. When she is hungry, she tweets 4 times per minute. And when she watches herself in the mirror, she tweets 45 times per minute. During a time period where she is happy for 20 minutes, hungry for 20 minutes, and watches her reflection for 20 minutes, what is the total number of times she will tweet?
[Answer]In 20 minutes, she happy tweets for 20 * 18 = 360 times. In 20 minutes, she hungry - tweets for 20 * 4 = 80 times. In 20 minutes, she tweets at her reflection 20 * 45 = 900 times. Altogether, she tweets 360 + 80 + 900 = 1340 times. The answer is 1340.

On the second day, Penn made $10 + $4 = $14. On the 3rd day, she made $14 + $4 = $18. On the 4th day , she made $18 + $4 = $22. On the 5th day, she made $22 + $4 = $26. After 5 days, Penn made a total of $10 + $14 + $18 + $22 + $26 = $90. The answer is 90.
