Two trains, 200 km apart, are moving toward each other at the speed of 50 km/hour each. A fly takes off from one train flying straight toward the other at the speed of 75 km/hour. Having reached the other train, the fly bounces off it and flies back to the first train. The fly repeats the trip until the trains collide and the bug is squashed.

relative speed of two trains approaching each other will be 50+50=100kph
Dist between them 200km .
hence time for collision =200/100=2hrs
For this 2hrs fly can travel(theoretically)=75kph*2=150km.
I find this one the easiest approach to solve.
Waiting for the out of box solution.

Lets consider time = x
So the equation will be
50x+50x=200
X=2 hours
Fly speed = 75kmph
75*2=150 km
