Answer 2

Problem Analysis

We are given that a pedestrian walks from a village to a town at a speed of 4 km/h. After 2 hours, a cyclist leaves the town and meets the pedestrian. The cyclist's speed is 9 km/h. We need to find the distance between the village and the town, given that the pedestrian has walked 16 km.

Solution

Let's break down the problem step by step:

1. We know that the pedestrian walks at a speed of 4 km/h. After 2 hours, the pedestrian has covered a distance of 4 km/h * 2 h = 8 km.2. We are given that the pedestrian has walked a total of 16 km. Therefore, the remaining distance between the pedestrian and the town is 16 km - 8 km = 8 km. 3. Now, we need to find the time it takes for the cyclist to cover the remaining distance of 8 km. The cyclist's speed is 9 km/h, so the time taken is 8 km / 9 km/h = 8/9 h. 4. Since the cyclist and the pedestrian meet after 2 hours, we can set up the equation: 2 hours + 8/9 hours = total time taken. 5. Solving the equation, we find that the total time taken is 26/9 hours. 6. Finally, we can find the distance between the village and the town by multiplying the total time taken by the pedestrian's speed: (26/9 hours) * (4 km/h) = 104/9 km.

Answer

The distance between the village and the town is 104/9 km.
