Question: Audrey is 7 years older than Heracles. In 3 years, Audrey will be twice as old as Heracles is now. How old is Heracles now?
Answer: Step-by-step reasoning process: Since Audrey is older than Heracles by 7 years, in 3 years he will be 10 years older than Heracles' current age. In 3 years he will be double Heracles' current age 10 * 2 = 20. Heracles is 10.
So the answer is 10.

Question: James has 20 pairs of red socks and half as many black socks. He has twice as many white socks as red and black combined. How many total socks does he have combined?
Answer: Step-by-step reasoning process: He has 20 / 2 = 10 black socks. So he has 20 + 10 = 30 black and red socks. So he has 30 * 2 = 60 white socks. So he has 60 + 30 = 90 total socks.
So the answer is 90.

Question: Every 10 seconds, there is a car collision, and every 20 seconds there is a big crash. How many accidents overall will happen in 4 minutes?
Answer:
Step-by-step reasoning process: 1 minute is 60 seconds, so 4 minutes is 4 * 60 = 240 seconds. During this time there would be 240 / 20 = 12 big crashes. And also 240 / 10 = 24 car collisions. So in total during 4 minutes there would be 12 + 24 = 36 accidents.
So the answer is 36.
