[Question]Aria has twice as many high school credits as Emily, who has twice the number of high school credits as Spencer. If Emily has 20 credits, what's twice the total number of high school credits the three have?
[Answer]If Emily has 20 credits, and Aria has 2 times as many, then Aria has 2 * 20 = 40 high school credits. Emily has twice the number of high school credits Spencer has, meaning Spencer has 20 / 2 = 10 high school credits. Altogether, the three have 40 + 20 + 10 = 70 high school credits. Twice the total number of high school credits the three have is 2 * 70 = 140. The answer is 140.
Q: Maddie watches 8 episodes of a TV show this week. Each episode is about 44 minutes long. If she watches 138 minutes of the show on Monday. She does not watch any TV on Tuesday and Wednesday. On Thursday, she watches 21 minutes. On Friday, she watches 2 episodes. How many more minutes did she watch over the weekend?
A: Maddie watches a total of 8 * 44 = 352 minutes of the TV show during the week. On Friday, she watches 2 * 44 = 88 minutes. On Monday, Thursday, and Friday, she watches 138 + 21 + 88 = 247 minutes. Thus, on the weekend she watches 352 - 247 = 105 minutes of the TV show. The answer is 105.
Question: A father and a son start approaching each other at the same time from opposite ends of a hallway that is 16m long. If the father is walking three times as fast as the son, at what distance from the father's end of the hallway will they meet?
Answer: Since the father is walking 3 times as fast as his son, their speeds are in a ratio of 3:1 respectively. They started at the same time so they will cover distance at the same ratio of 3:1. Each portion of the distance they covered is 16 / (3 + 1) = 4m. The father covered three portions of the distance which is 3 * 4m = 12m from his end. The answer is 12.

[Question]A library cabinet houses five ancient scrolls. The first scroll is 4080 years old. If each scroll is older than the last by half as many years as the last scroll’s age, how old is the fifth scroll?
[Answer]
The second scroll is 4080 + 4080 / 2 = 4000 + 2040 = 6120 years old. The third scroll is 6120 + 6120 / 2 = 6120 + 3060 = 9180 years old. The fourth scroll is 9180 + 9180 / 2 = 9180 + 4590 = 13770 years old. The fifth scroll is 13770 + 13770 / 2 = 13770 + 6885 = 20655 years old. The answer is 20655.
