Question

The table shows the World Records for male sprinters in 2011 over different
distances. Complete the table by calculating the average speed of each runner.
Distance in metres
100
200
400
Time in seconds
9.58
19.19
43.18
Speed in m/s
Q:Over which distance do
sprinters have the greatest
average speed?​

Answer 1

Answer:

runner1= 100/9.58

           =>10.43 m/s

runner2=200/19.19  

            =>10.42 m/s

runner3= 400/43.18

            => 9.26 m/s

Therefore, over the distance of 100m sprinters have the gratest speed.

Side note: You could add"Due to the short distance sprinters do not have to pace themselves."

(I think I have misunderstood on how to use the valuesof distance and time. Otherwise my claculations are correct  

Explanation:

speed = distance divided by time
