To find how long the pedestrian was on the way, we use the formula: t = L / V, where V is the speed, and t is the travel time, L is the distance. Since the pedestrian traveled 10 km at a speed of 5 km / h, then t = 10/5 = 2 hours and 12 km at a speed of 6 km / h, then t = 12/6 = 2 hours. The pedestrian was on the way: 2 hours + 2 h = 4 h.
Answer: the pedestrian was on the way for 4 hours.
