Velocity is the directional speed of a moving object, expressing the rate of change in position as perceived from a particular frame of reference and measured against a particular time standard. Velocity is a fundamental concept in kinematics, a branch of classical mechanics that describes the motion of objects.
Average Velocity =
According to the Question:
Given that:
Initial Odometer (S1) = 400 Kilometre
Final Odometer (S2) = 868 Kilometre
Time (t) = 04 hours.
We know that:
Average Speed (v) =
Now,
Converting km/hr to m/s and multiplying km/hr by
We get:
Or,
