The pedestrian walked at the same speed of 4 km. What path can a skier go if his speed is 2 times the speed of a pedestrian, and the travel time is 3 times more?
Values are called directly proportional if, when one increases several times, the second increases by the same amount.
At a constant speed, time and distance are directly proportional.
If the speed of the skier is twice that of the pedestrian, then he will cover 8 km in the same time that the pedestrian walked 4.
And, if you increase the time three times, then the distance will increase three times:
8 * 3 = 24 (km).
Answer. 24 km.
