Problem Analysis

We are given that the distance between a village and a town is 36 km. A cyclist starts from the village and travels towards the town at a speed of 12 km/h. At the same time, a postman starts from the town and walks towards the village at a speed of 6 km/h. We need to determine the time it takes for them to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed.

Let's calculate the time it takes for the cyclist to reach the meeting point: - Distance traveled by the cyclist = 12 km/h * t (where t is the time in hours) - Distance traveled by the postman = 6 km/h * t

Since the total distance between the village and the town is 36 km, the sum of the distances traveled by the cyclist and the postman should be equal to 36 km:

12t + 6t = 36

Simplifying the equation:

18t = 36

Dividing both sides by 18:

t = 2

Therefore, it will take 2 hours for the cyclist and the postman to meet.

Answer

The cyclist and the postman will meet after 2 hours.
