Two trains are on the same line, 100 kms apart, heading towards each other. The first train is moving at 60 kms/hr while the other train is at 40 kms/hr. A fly sitting on the second train starts travelling towards the other train at 50 kms/hr. Upon reaching the other engine, it instantaneously turns around, and heads back to the other engine. This is repeated until the two trains crash and the fly is annihilated at the same time. How far does the fly travel before it is "splatted"?
