Downhill skiers race over a course that's 3,500 m long in 2 minutes, 10

seconds. What is their approximate average speed for this course?

O

A. 1.67 m/s

O

B. 26.9 m/s

O

c. 19.2 m/s

O

D. 1,667 m/s

=26.92 m/s

Explanation:

Speed is calculated as a ratio of the total distance covered (It is directionless) to the total time taken to cover the distance.

Average speed = total distance/total time

=x/t

Total distance from the question = 3500m

Total time taken to cover the above distance = 2*60 + 10=130 Seconds

Therefore, average speed = 3500m/130 s

=26.92 m/s
