Subject: Fly problem, alternative solution?

Everybody has heard the problem:

Two trains 200 miles apart are moving toward each other;
each one is going at a speed of 50 miles per hour.
A fly starting on the front of one of them flies back and forth
between them at a rate of 75 miles per hour. It does this until the
trains collide and crush the fly to death. What is the total distance
the fly has flown?

The solution is simple, using s=t*v, but is ther another way
of solving it by trough limit?
