Question: John is half times younger than his father, who is 4 years older than John's mother. If John's father is 40 years old, what's the age difference between John and his mother?
Answer: John is half times his father's age. Thus 1 / 2 * 40 = 20 years. Since the mother is 4 years younger than the father, she is 40 - 4 = 36 years old. The age difference between John and his mother is 36 - 20 = 16 years. The answer is 16.
Q: Joan wants to visit her family who live 480 miles away. If she drives at a rate of 60 mph and takes a lunch break taking 30 minutes, and 2 bathroom breaks taking 15 minutes each, how many hours did it take her to get there?
A:
The driving time is 480 / 60 = 8 hours. The time for breaks was 30 + 15 + 15 = 60 minutes. So she spent 60 / 60 = 1 hour for rest stops. So it took her 8 + 1 = 9 hours. The answer is 9.
