Problem Analysis

We are given that a cyclist and a rider start simultaneously from a village in opposite directions. The rider's speed is 15 km/h, and the cyclist's speed is 12 km/h. We need to find the distance between them after 2 hours.

Solution

To find the distance between the cyclist and the rider after 2 hours, we need to calculate the total distance covered by each of them in 2 hours and then find the difference between these distances.

Let's calculate the distance covered by the cyclist and the rider separately.

The distance covered by the cyclist in 2 hours can be calculated using the formula:

Distance = Speed × Time

For the cyclist: Distance_cyclist = Speed_cyclist × Time = 12 km/h × 2 h = 24 km Similarly, the distance covered by the rider in 2 hours can be calculated using the same formula:

Distance_rider = Speed_rider × Time = 15 km/h × 2 h = 30 km Now, we can find the distance between them by subtracting the distance covered by the cyclist from the distance covered by the rider:

Distance_between = Distance_rider - Distance_cyclist = 30 km - 24 km = 6 km

Therefore, the distance between the cyclist and the rider after 2 hours is 6 km.

Answer

The distance between the cyclist and the rider after 2 hours is 6 km.
