Question: Mark is injured so decides to spend more time reading. He used to read 2 hours a day but increased that by 150%. Before he read 100 pages a day. How many pages does he read a week now?
Answer: His reading speed is 100 / 2 = 50 pages a day. He reads 2 * 1.5 = 3 hours more now than before. So now he reads 2 + 3 = 5 hours per day. That means he reads 5 * 50 = 250 pages per day. So he reads 250 * 7 = 1750 pages a week. The answer is 1750.
[Question]A train takes 4 hours to reach a destination at a speed of 50 miles per hour. How long would it take if it traveled at 100 miles per hour instead?
[Answer]The distance to the destination is 4 hours * 50 miles / hour = 200 miles. Traveling at 100 miles per hour, it will take 200 miles / (100 miles / hour) = 2 hours. The answer is 2.
Q: If Pam is currently twice as young as Rena is, and in 10 years Rena will be 5 years older than her, how old is Pam now?
A: If Rena will be 5 years older than Pam in 10 years, this means they have a 5 year age gap. Therefore, to be twice Pam's age, Rena would have to be 5 * 2 = 10 years old. This means that Pam is currently 10 - 5 = 5 years old. The answer is 5.
