Answer 3

The Question

A skier traveled from a village to a railway station at a speed of 12 km/h. This journey took him 3 hours. How fast did he travel on the return journey if it took him 4 hours?

Breaking Down the Problem

The key facts are: - Distance from village to station - Speed on first journey was 12 km/h - Time taken for first journey was 3 hours - Time taken for return journey was 4 hours

Solving the Problem

To solve this, we use the formula: Distance = Speed x Time

For the first journey: Distance = 12 km/h x 3 hours Distance = 36 km

For the return journey: Distance = ? km/h x 4 hours Distance = 36 km

Using the formula again: 36 km = ? km/h x 4 hours ? km/h = 36/4 = 9 km/h

Therefore, the speed of the skier on the return journey was 9 km/h.
