1. points
A, B and C start running simultaneously from the points P, Q and R respectively on a circular track. The distance (when measured along the track) between any two of the three points P, Q and RisLand the ratio of the speeds of A, B and £T;2:3. If A and B run in opposite directions while B and Crun in the same direction, what is the distance run by C before A，B and C meet for the first time? Answer: never meet
