A person walking at a constant rate of 6 miles per hour is passed by a cyclist traveling in the same direction along the same path at 10 miles per hour. the cyclist stops to wait for the person 10 minutes after passing her, while the person continues to walk at her constant rate, how many minutes must the cyclist wait until the person catches up?
Choose one:
A) 15min
B) 11min
C) 20min
D) 40min
E) 1hour
After passing the person the cyclist travels for 10 minutes at a rate of 10 miles/hour.   In those 10 mins the cyclist travels a distance of 5/3 miles.   In those 10 mins the person travels a distance of 1 miles.   So the person still has to cover 2/3 miles to meet the waiting cyclist.   The person will need 1/9 hours or 11 mins to cover the remaining 2/3 miles.   The answer is 11min
