A train travels with a speed of $60$ km/h from station A to station B and then comes back with a speed $80$ km/h from station B to station A. Find the average velocity of train.

Open in App

Solution

We know, $Average velocity = \frac{total displacement}{total time taken}$

Since the train starts the journey and end the journey at the same station, the displacement is zero. Hence, average velocity is also zero.
