Question:

 

 Two trains are traveling on the same straight track towards one another at a speed of 50 km/hr each. At the time they are 100 km apart, a fly starts flying from the front of one train to the front of the other. It then turns around and flies to the front of the original train and keeps going back and forth between the 2 trains. If the fly travels on a straight line above the track at a constant speed of 100 km/hr, how much distance will it cover before it meets its tragic fate?
