Answer 3

Problem Analysis

We have two skiers who start at the same point and move in opposite directions. The speed of one skier is 15 km/h, and the speed of the other skier is 10 km/h. We need to find out how far apart they will be after 1 hour, 2 hours, and 3 hours.

Solution

To find the distance between the two skiers after a certain amount of time, we can use the formula: distance = speed * time.

1. After 1 hour: - The first skier will have traveled 15 km (15 km/h * 1 h). - The second skier will have traveled 10 km (10 km/h * 1 h). - Therefore, they will be 25 km apart after 1 hour.

2. After 2 hours: - The first skier will have traveled 30 km (15 km/h * 2 h). - The second skier will have traveled 20 km (10 km/h * 2 h). - Therefore, they will be 50 km apart after 2 hours.

3. After 3 hours: - The first skier will have traveled 45 km (15 km/h * 3 h). - The second skier will have traveled 30 km (10 km/h * 3 h). - Therefore, they will be 75 km apart after 3 hours.

So, the two skiers will be 25 km apart after 1 hour, 50 km apart after 2 hours, and 75 km apart after 3 hours.

Answer

The two skiers will be: - 25 km apart after 1 hour, - 50 km apart after 2 hours, and - 75 km apart after 3 hours.
