World class speed skaters can skate a 3,000-m course in about 4 minutes. what is their average speed for this course. a. 12.5m/s b. 1.33m/s c. 13.3m/s d. 1.25m/s

A. 12.5 m/s.

The average speed is defined as the relationship between the displacement made by a body and the total time it took to perform it.

The formula that will allow you to calculate the average speed is:

v = d/t, where d is the traveled distance and t the time it took to travel the distance.

We hace to convert 4 minutes to second:

(60 s/1 min)*(4 min) = 240 s

So, the average speed is:

v = 3000 m/240 s

v = 12.5 m/s  

not too sure but maybe in the hot springs.
