Problem Analysis

We are given that a rider on a horse is traveling from a village to a city at a speed of 12 kilometers per hour, while at the same time, a mailman is traveling from the city to the village at a speed of 4 kilometers per hour. The distance between the city and the village is 48 kilometers. We need to determine when and where the rider and the mailman will meet.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed between the rider and the mailman is the sum of their individual speeds. In this case, the relative speed is 12 + 4 = 16 kilometers per hour.

To find the time it takes for the rider and the mailman to meet, we can divide the distance between the city and the village by the relative speed:

Time = Distance / Relative Speed

Substituting the given values, we have:

Time = 48 kilometers / 16 kilometers per hour

Simplifying, we find:

Time = 3 hours

Therefore, the rider and the mailman will meet after 3 hours of travel.

To find the location where they meet, we can multiply the time it takes for them to meet by the speed of the rider:

Distance traveled by the rider = Time * Rider's speed

Substituting the values, we have:

Distance traveled by the rider = 3 hours * 12 kilometers per hour

Simplifying, we find:

Distance traveled by the rider = 36 kilometers

Therefore, the rider and the mailman will meet 36 kilometers away from the village.

Answer

The rider and the mailman will meet after 3 hours of travel, 36 kilometers away from the village.
