Answer:
Average speed = 9.91 m/s
Explanation :
Total distance covered by a runner = 200 m
Time taken to complete this distance = 20.19 sec
We need to find the average of runner speed in meter/sec
We use the speed, distance, time formula
![speed = \frac{distance}{time}](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
speed = ![\frac{200}{20.19}](https://tex.z-dn.net/?f=%5Cfrac%7B200%7D%7B20.19%7D)
Average speed = 9.91 m/s
that's the final answer.
