A pedestrian walks along a highway at a speed of 5 km/h. Buses travel along this highway in both directions at the same speed, meeting every 5 minutes. At 12 o'clock, the pedestrian noticed that the buses met near him and, continuing to walk, began counting the passing and overtaking buses. At 2 o'clock, the buses met again near him. It turned out that during this time, the pedestrian encountered four more buses than those overtaking him. Find the speed of the bus.
