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
