Problem Analysis

We are given that a service dog chased after a border violator when there was a distance of 1.8 km between them. The dog's speed is 19 km/h, and it caught up to the violator in 0.2 hours. We need to find the speed at which the violator was running.

Solution

To find the speed at which the violator was running, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the violator using this formula.

Calculation

Given: - Distance between the dog and the violator = 1.8 km - Dog's speed = 19 km/h - Time taken for the dog to catch the violator = 0.2 hours

Using the formula Speed = Distance / Time, we can substitute the given values:

Speed of the violator = 1.8 km / 0.2 hours

Calculating the speed:

Speed of the violator = 9 km/h

Therefore, the violator was running at a speed of 9 km/h.

Answer

The violator was running at a speed of 9 km/h.
