Trains
There are two trains traveling 60 mph towards each other. When they are 120 miles apart, a fly leaves one train heading towards the other at 100 mph. As soon as it reaches the other train, it immediately flies back towards the first train. It continues doing this until the trains collide. How much distance does the fly cover before the trains collide?

The trains will collide in an hour. So the fly travels 100 miles in that time
