Collision of trains

Q: Two trains 200km apart are moving towards each other on the same track. Train A has a speed of 120km/hr, while Train B travels at 80km/hr. A bug starts flying from Train A and moves towards Train B at a speed of 160km/hr. On colliding with train B, it bounces back and starts moving towards Train A. On colliding with it, it bounces back, and repeats the process until both the trains collide. Find the distance traveled by the bug.
