Answer 1

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 = (distance)/(time)`

speed =
`(200)/(20.19)`

Average speed = 9.91 m/s

that's the final answer.
