Answer:
v = 5 m/s.
Explanation:
Given that,
Mass of a student, m = 55 kg
He traveled 200 m in 40 s
We need to find the student’s average speed. Total distance divided by total time is equal to average speed. It can be written as :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{200\ m}{40\ s}\\\\=5\ m/s[/tex]
So, the average speed of the student is 5 m/s.
