Answer 2

Problem Analysis

Two skiers are moving towards each other. The distance between them is 72 km. The first skier has a speed of 8 km/h, and the second skier has a speed of 10 km/h. We need to determine how many hours it will take for them to meet.

Solution

To find the time it takes for the skiers to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two skiers since they are moving towards each other.

Let's calculate the time it takes for the skiers to meet.

Distance = 72 km

Relative Speed = Speed of Skier 1 + Speed of Skier 2 = 8 km/h + 10 km/h = 18 km/h

Time = Distance / Relative Speed = 72 km / 18 km/h = 4 hours

Therefore, the skiers will meet after 4 hours.

Answer

The two skiers will meet after 4 hours.
