Two towns A and B are connected by a regular bus service with a bus leaving in either direction every T minutes. A man cycling with a speed of 40 km/h in the direction A to B notices that a bus goes past him every 24 min in the direction of his motion, and every 12 min in the opposite direction. What is the period T of the bus service and with what speed (assumed constant) do the buses ply on the road?
