Problem Analysis

We are given that the distance from the city to the village is 24 km. A person starts walking from the city at a speed of 6 km/h. We need to determine the position of the pedestrian on a distance scale after 1 hour, 2 hours, and 3 hours, and also find out when the person will reach the village.

Solution

To determine the position of the pedestrian on the distance scale after a certain time, we can use the formula:

Distance = Speed x Time

Let's calculate the position of the pedestrian after 1 hour, 2 hours, and 3 hours.

1. After 1 hour: - Speed = 6 km/h - Time = 1 hour - Distance = Speed x Time = 6 km/h x 1 hour = 6 km

2. After 2 hours: - Speed = 6 km/h - Time = 2 hours - Distance = Speed x Time = 6 km/h x 2 hours = 12 km

3. After 3 hours: - Speed = 6 km/h - Time = 3 hours - Distance = Speed x Time = 6 km/h x 3 hours = 18 km

Now, let's determine when the person will reach the village. We know that the distance from the city to the village is 24 km and the person is walking at a speed of 6 km/h.

To find the time it takes to cover a certain distance, we can use the formula:

Time = Distance / Speed

Let's calculate the time it takes to reach the village.

- Distance = 24 km - Speed = 6 km/h - Time = Distance / Speed = 24 km / 6 km/h = 4 hours

Therefore, the person will reach the village after 4 hours.

Summary

- After 1 hour, the person will be 6 km away from the city. - After 2 hours, the person will be 12 km away from the city. - After 3 hours, the person will be 18 km away from the city. - The person will reach the village after 4 hours.
