Two cyclists, 120 Km apart, approach each other, each pedalling at 20 Km per hour. A fly starts at one cyclist, flies towards the other one, then bounces off it and thus flies back and forth between the two cyclists at 25 Km per hour. When the cyclists meet head on and squash the fly between them, how far has the fly flown while going back and forth?
