[Question]When you take Hiram's age and then add 12, you get 4 less than twice Allyson's age. If Hiram is 40 years old, how old is Allyson?
[Answer]If Hiram's age is 40, when you add 12, his age becomes 40 + 12 = 52. If you add 4 from Hiram's age after adding twelve to his age, you get 52 + 4 = 56, which is twice Allyson's age. Allyson's age is 56 / 2 = 28 years. The answer is 28.
Q: Tom paints a room that has 5 walls. Each wall is 2 meters by 3 meters. John can paint 1 square meter every 10 minutes. He has 10 hours to paint everything. How many hours does he have to spare?
A: Each wall is 2 * 3 = 6 square meters. So each wall takes 6 * 10 = 60 minutes to paint. So it takes 60 / 60 = 1 hour to paint each wall. That means in total it takes 5 * 1 = 5 hours to paint. So he has 10 - 5 = 5 hour left after finishing painting. The answer is 5.
Question: Bob, a marathon runner, is preparing for a race. He runs a total of 70 miles in the 3 days leading up to the race. On day one he runs 20 percent of the total miles and on day 2 he runs 50 percent of the remaining miles. How many miles does he run on day three to complete the 70 miles?
Answer: Day 1: 70(.20) = 14 miles. 70 - 14 = 56 miles remaining. Day 2:56 / 2 = 28 miles. 56 - 28 = 28 miles remaining. The answer is 28.
Q: John takes a 10-minute shower every other day for 4 weeks. If his shower uses 2 gallons of water per minute. How much water does he use in those 4 weeks?
