The runner’s average speed will be 8.7 m/sec.Average speed is the ratio of the total distance to the total time.

The total distance traveled by an object divided by the total time taken is the average speed.

The given data in the problem is;

d is the distance traveled = 200-meter

t is the time period = 23 seconds.

v is the average velocity to be found;

The average velocity is found as;

[tex]\rm v = \frac{d}{t} \\\\ \rm v = \frac{200}{23} \\\\ v=8.7 \ m/sec[/tex]

Hence the runner’s average speed will be 8.7 m/sec.
