A pedestrian leaves point A with a speed of v1 = 5 km/h.
After 3 hours, a cyclist follows him from the same place at a speed of v2 = 20 km/h.
But a car starts from point B, 50 km away at the same time as the cyclist.
Calculate the distance and time at which the cyclist overtook the pedestrian and the speed v the car had to travel for everyone to meet at the same time.
