The average velocity of the runner for the given displacement and time of motion is 5 m/s.
The given parameters:
- Distance covered, d = 400 m
- Time of motion, t = 80 s
The average velocity of the runner is determined by dividing the total displacement by the time of motion as shown below;
[tex]v= \frac{Displacement }{time} \\\\v = \frac{400}{80 } \\\\v = 5 \ m/s[/tex]
Thus, the average velocity of the runner for the given displacement and time of motion is 5 m/s.
