The average velocity is -4.17 m/s
Explanation:
The average velocity of a body is given by:
[tex]v=\frac{d}{t}[/tex]
where
d is the displacement of the body
t is the time elapsed
For the student in this problem, we have:
Initial position: [tex]x_i = 450 m[/tex]
Final position: [tex]x_f = 200 m[/tex]
So the displacement is
[tex]d=x_f -x_i = 200 - 450 = -250 m[/tex]
The time elapsed is
t = 60 s
Therefore, the average velocity is
[tex]v=\frac{-250}{60}=-4.17 m/s[/tex]
Where the negative sign means the student is moving towards the origin.
