Consider two cities P and Q, between which consistent bus service is available in both directions every x minutes. A morning jogger is jogging towards Q from P with a speed of 10 km/h. Every 18 min a bus crosses this jogger in its own direction of motion and every 6 min another bus crosses in opposite direction.
