Problem Analysis

We are given that a cyclist and a pedestrian start from two different locations, Okunevo and Karaseva, which are 17 km apart. The cyclist has a speed of 12 km/h, while the pedestrian has a speed of 5 km/h. The cyclist reaches Karaseva and immediately turns back without changing speed. We need to determine how long it will take for them to meet.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between the cyclist and the pedestrian is the sum of their individual speeds. In this case, the relative speed is 12 km/h + 5 km/h = 17 km/h.

Since the distance between Okunevo and Karaseva is 17 km, and the relative speed is also 17 km/h, it will take them 1 hour to meet. This is because the relative speed is equal to the distance traveled divided by the time taken.

Therefore, the cyclist and the pedestrian will meet 1 hour after they start their respective journeys.

Answer

The cyclist and the pedestrian will meet 1 hour after they start their respective journeys.
