From point A to point B, which are 40 km apart, a pedestrian set out at 4:00 AM, and a cyclist set out at 7:20 AM. The cyclist caught up with the pedestrian exactly halfway between A and B, after which both continued their journey. A second cyclist with the same speed as the first cyclist set out from B to A at 8:30 AM and met the pedestrian one hour after the pedestrian's meeting with the first cyclist. Find the speeds of the pedestrian and the cyclists.
