Problem Analysis

Two motorcyclists are traveling in opposite directions from a village. After 2 hours, the distance between them is 166 km. The speed of the first motorcyclist is 45 km/h. We need to find the speed of the second motorcyclist.

Solution

Let's denote the speed of the second motorcyclist as x km/h.

The total distance covered by both motorcyclists after 2 hours is the sum of their individual distances, which is equal to 166 km.

Using the formula: distance = speed × time, we can write the equation: 45 km/h × 2 h + x km/h × 2 h = 166 km

Solving for x will give us the speed of the second motorcyclist.

Calculation

45 km/h × 2 h + x km/h × 2 h = 166 km 90 km + 2x = 166 km 2x = 166 km - 90 km 2x = 76 km x = 76 km / 2 h x = 38 km/h

Answer

The speed of the second motorcyclist is 38 km/h.
