Q: Jessica just got her driving permit. She must complete 50 hours of driving with a parent to get her driver's license. It takes 20 minutes to drive to school. If she drives to and from school every day, how many school days will it take Jessica to meet the 50-hour driving requirement?
A: Jessica will drive 20 minutes, twice every school day (to and from school), so 20 minutes x 2 trips = 40 minutes each day. There are 60 minutes in 1 hour, so 50 hours of driving x 60 minutes / hour = 3,000 minutes. If you take the 3,000 minutes she needs to drive / 40 minutes driving each day = 75 school days to drive 50 hours. The answer is 75.

Q: Lavinia's daughter is 10 years younger than Katie's daughter. Lavinia's son is 2 times the age of Katie's daughter. If Katie's daughter is 12 years old, how many years older is Lavinia's son than Lavinia's daughter?
A: Lavinia's daughter is 12 - 10 = 2 years old. Lavinia's son is 12 * 2 = 24 years old. Lavinia's son is 24 - 2 = 22 years older than Lavinia's daughter. The answer is 22.

Q: There is a rectangle that is 4 inches wide. If the rectangle's perimeter is 30 inches, what is the area of the rectangle?
A:
Twice the height of the rectangle is 30 inches - 2 * 4 inches = 22 inches. The rectangle's height is 22 inches / 2 = 11 inches. The area of the rectangle is 4 inches * 11 inches = 44 square inches. The answer is 44.
