The skier covered 300 m in 6 seconds. Find the average speed of the skier over the course.

The skier moved evenly. For every second of his movement, he covered the same distance.
The distance traveled by a skier per second is called the speed of movement.
We recall the formula for determining the speed with uniform movement:
V = S / t;
V is the speed of uniform movement;
S – distance traveled;
t – travel time.
Substitute the distance and time values into the formula and determine the skier’s speed:
V = 300 m / 6 seconds = 50 m / s.
Answer: the speed of the skier was 50 m / s.
