Answer 1

Calculation of the Skier's Speed on the Return Trip

To determine the speed at which the skier traveled on the return trip, we can use the formula:

Speed = Distance / Time

Given that the skier traveled a distance from the village to the train station in 3 hours at a speed of 12 km/h, we can calculate the distance using the formula:

Distance = Speed * Time

Let's calculate the distance traveled by the skier on the outbound trip:

Distance = 12 km/h * 3 hours = 36 km

Now, let's calculate the speed of the skier on the return trip. We know that the skier took 4 hours to cover the same distance of 36 km. Using the formula:

Speed = Distance / Time

Speed = 36 km / 4 hours = 9 km/h

Therefore, the skier traveled at a speed of 9 km/h on the return trip.
