Given data:
* The distance covered in the given case is 150 meters.
* The time taken to cover the distance is 18 seconds.
Solution:
In the case of uniform motion of the body, the average speed of the body is the ratio of distance traveled and time taken by the body.
Thus, the average speed of the given person is,
[tex]\begin{gathered} v_a=\frac{150}{18} \\ v_a=8.33ms^{-1} \end{gathered}[/tex]Thus, the average speed in m/s is 8.33 m/s.
