There is a circle which is 1 meter in circumference and a point marked on it. Two cockroaches start running in the same direction from the marked point with different speeds. Whenever the fast one would catch up with the slow one, the slow one would instantly turn around and start running in tho other direction with the same speed. Whenever they would meet face-to-face, the fast one would instantly turn around and start running in tho other direction with the same speed. How far from the marked point could their 100th meeting be?
