Answer 2

Problem Analysis

We are given that a skier starts chasing a pedestrian when the distance between them is 960 meters. The skier catches up to the pedestrian in 8 minutes. We need to find the speed of the skier, given that the pedestrian's speed is 80 meters per minute.

Solution

To find the speed of the skier, we can use the formula:

Speed = Distance / Time

Let's calculate the speed of the skier using this formula.

Calculation

Given: - Distance between the skier and the pedestrian = 960 meters - Time taken to catch up = 8 minutes - Speed of the pedestrian = 80 meters per minute

Using the formula Speed = Distance / Time, we can substitute the given values:

Speed of the skier = 960 meters / 8 minutes

Simplifying the equation:

Speed of the skier = 120 meters per minute

Therefore, the speed of the skier is 120 meters per minute.

Answer

The speed of the skier is 120 meters per minute.
