The average speed of the runner is 8.7m/s.
Therefore, Option C) 8.7m/s is the correct answer.
Given the data in the question;
Distance covered; [tex]d = 200m[/tex]
Time taken; [tex]t = 23s[/tex]
Average speed; [tex]s = \ ?[/tex]
Speed is the rate at which an object covers a certain distance. It is expressed as:
[tex]s = \frac{d}{t}[/tex]
Where s is speed, d is distance and t is time taken.
We substitute our given distance into the equation
[tex]s = \frac{200m}{23s} \\\\s = 8.6956m/s\\\\s = 8.7m/s[/tex]
The average speed of the runner is 8.7m/s
Therefore, Option C) 8.7m/s is the correct answer.
