Question 2

Two cyclists are each pedaling towards each other at 20 mph. When they are 2 miles apart, a very fast fly leaves the front of one bicycle at 60 mph and heads toward the other bicycle. When he reaches it, he immediately reverses direction and flies back to the first bicycle at 60 mph. This pattern continues until the bicycles meet. What total distance did the fly travel?

3 miles
