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 :
![v=\dfrac{d}{t}\\\\v=\dfrac{200\ m}{40\ s}\\\\=5\ m/s](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Bd%7D%7Bt%7D%5C%5C%5C%5Cv%3D%5Cdfrac%7B200%5C%20m%7D%7B40%5C%20s%7D%5C%5C%5C%5C%3D5%5C%20m%2Fs)
So, the average speed of the student is 5 m/s.

What is hierarchy?</h3>
A hierarchy is an arrangement of items (objects, names, values, categories, and so on). Hierarchy is a key concept in many disciplines, including architecture, philosophy, design, mathematics, computer science, organizational theory, systems theory, systematic biology, and social sciences.
A hierarchy can connect entities directly or indirectly, and it can connect entities vertically or diagonally. In a hierarchical system, the only direct links are to one's immediate superior or to one of one's subordinates, though a largely hierarchical system can also incorporate alternative hierarchies. Hierarchical links can extend "vertically" upwards or downwards by following a path with multiple links in the same direction.
