Question

A 55 kg student was riding his skateboard to school. He traveled 200 meters in 40 seconds. What was the student’s average speed in meters per second

Answer 1

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 :

$v=\dfrac{d}{t}\\\\v=\dfrac{200\ m}{40\ s}\\\\=5\ m/s$

So, the average speed of the student is 5 m/s.
