- Problem: Two Trains and a Fly 1 answer
Two cyclists, 120 miles apart, approach each other, each pedaling at 10 miles per hour. A fly starts at one cyclist and flies back and forth between the cyclists at 15 miles per hour. When the cyclists come together (and squash the fly between them), how far has the fly flown?
I know that I am supposed to find some sort of series here, but I don't really know how to approach this. How do I find the terms?
