Answer 2

Problem Analysis

Two cyclists start simultaneously from two different villages and meet after 3 hours. The first cyclist travels at a speed of 12 km/h, and the second cyclist travels at a speed of 14 km/h. We need to determine the distance between the two villages.

Solution

To find the distance between the two villages, we can use the formula: distance = speed × time.

Let's denote the distance between the two villages as d.

The first cyclist travels at a speed of 12 km/h for 3 hours, so the distance traveled by the first cyclist is 12 km/h × 3 h = 36 km.

The second cyclist travels at a speed of 14 km/h for 3 hours, so the distance traveled by the second cyclist is 14 km/h × 3 h = 42 km.

Since the two cyclists meet after 3 hours, the sum of the distances traveled by both cyclists should be equal to the distance between the two villages.

Therefore, we have the equation: 36 km + 42 km = d.

Simplifying the equation, we find that d = 78 km.

Answer

The two villages are located at a distance of 78 km from each other.
