Answer 2

Problem Analysis

Two skiers start simultaneously from two villages and meet each other after 2 hours. The distance between the villages is 48 km, and the speed of one skier is given as 13 km/h. We need to determine the speed of the second skier.

Solution

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

We can use the formula: Speed = Distance / Time to calculate the speed of each skier.

The first skier travels the entire distance between the villages in 2 hours, so their speed is: Speed of the first skier = Distance / Time = 48 km / 2 hours = 24 km/h.

The second skier also travels the same distance in 2 hours, so their speed is: Speed of the second skier = Distance / Time = 48 km / 2 hours = 24 km/h.

Therefore, the speed of the second skier is also 24 km/h.

Answer

The second skier traveled with a speed of 24 km/h.

Explanation

Both skiers started simultaneously and met each other after 2 hours. Since the distance between the villages is 48 km, the speed of each skier can be calculated using the formula: Speed = Distance / Time. The speed of the first skier is given as 13 km/h, and the speed of the second skier is calculated to be 24 km/h.
