A pedestrian and a cyclist left the village at the same time in opposite directions. When the cyclist traveled 22 km at a speed of 11 km h, the distance between them became 30 km. What was the speed of the pedestrian?

Let’s start the solution by determining the time spent by the cyclist. This is determined by the formula t = S / v, where t is time? S – distance, v – speed. So, we get t = 22/11 = 2 hours. The pedestrian spent the same amount of time. Next, we will determine the distance traveled by the pedestrian. If the distance between him and the cyclist is 30 km, and the cyclist has traveled 22 km, then the pedestrian has traveled 30-22 = 8 km. So, knowing the distance and time covered by the pedestrian, we will find the speed. v = S / t. We get v = 8/2 = 4 km / h.
Answer: Pedestrian speed is 4 km / h.
