ZENO'S PARADOX

Suppose that there are two trains on the same track, moving towards one another. Each train is going 50 miles per hour. At the moment when they are 100 miles apart and closing, a fly sitting on the nose of one of the trains takes off and flies ahead of it, straight down the track towards the other train. This is a very fast fly – let's say it is going 100 miles per hour.



When it gets to the nose of the other, oncoming train, it does a quick about face and flies back towards the first train again. When it reaches the first train, it again does an about face, and so on, flying back and forth between the trains until the fateful moment when the trains collide, and the fly is smashed between them.
Today's challenge: What was the total travel distance of the fly before it was smashed?
