Problem Analysis

We are given that two cyclists started simultaneously in the same direction. The speed of the first cyclist is 16 km/h. After one hour, the distance between them became 3 km. We need to find the speed of the second cyclist.

Solution

Let's assume the speed of the second cyclist is x km/h.

After one hour, the first cyclist has covered a distance of 16 km (since their speed is 16 km/h). The second cyclist has covered a distance of x km.

The difference in distance between them is 3 km. So, we can set up the following equation:

16 km - x km = 3 km

Simplifying the equation, we get:

16 km - 3 km = x km

13 km = x km

Therefore, the speed of the second cyclist is 13 km/h.

Answer

The speed of the second cyclist is 13 km/h.
