The average speed of the runner is 8.7m/s

Hence, Option C) 8.7m/s is the correct answer.

Given the data in the question;

  • Distance covered by runner; [tex]d = 200m[/tex]
  • Time taken; [tex]t = 23s[/tex]

Average speed; [tex]s =\ ?[/tex]

Speed is simply the rate at which a particle covers a given distance. It is expressed as:

Speed = Distance / Time

[tex]s = \frac{d}{t}[/tex]

We substitute our given distance into the equation;

[tex]s = \frac{200m}{23s} \\\\s = 8.7m/s[/tex]

The average speed of the runner is 8.7m/s

Hence, Option C) 8.7m/s is the correct answer.
