Circulating Tracks: Problem 2

Problem: A circular pathway had a length of 220 meters. Two kids, A and B, start at the same time, one clockwise, one non-clockwise, on two ends of the circle's diameter. Kid A's speed is 6 meters/second and Kid B's speed is 5 meters/second. If they keep traveling like this along the pathway, how many times will they meet within 210 seconds?
