Standard one is two trucks are driving toward each other. Each travels at 50 mp/h. At a distance of 100 miles apart a fly takes off from the windshield of one truck traveling toward the other at 80 mp/h. When it reaches the other truck it instantly turns around and flies toward the first - this continues until the trucks collide. What total distance does the fly cover?

This is poorly worded. It's not clear if the fly is moving 80 mph relative to the ground or 80 mph relative to the truck it flew off.
