Cathy and Cara begin running at the same time and they start at the same place on a straight path. Cathy runs at 10 miles per hour, and Cara runs at 5 miles per hour. After 12 minutes, Cathy stops to stretch. If it takes Cathy 24 minutes to stretch and Cara continues to run during this time, how many minutes will it take Cathy to catch up to Cara?	Choose the correct answer
A) 10
B) 12
C) 14
D) 16
E) 18
In 12 minutes, Cathy runs 2 miles.   In 36 minutes, Cara runs 3 miles.   Cathy can catch Cara at a rate of 5 miles per hour.   Since Cara is ahead by 1 mile, it will take Cathy 1 / 5 hours = 12 minutes to catch Cara.   The answer is 12.
