**Velocity - **It is defined as the displacement of the body per unit time.

**Velocity = **displacement travelled / time taken

**SI unit =** m/s (meter/second)

**Average Velocity - **The average velocity of a body is the total displacement travelled by the total time taken to cover this distance.

** Average velocity=** Total Displacement/Total Time taken

**Avg. Velocity (vavg) = **(Initial velocity + Final velocity)/2 = (u+v)/2

where, u = initial velocity, v = final velocity

**Example 1**: During first half of a journey by a body it travel with a speed of 40 km/hr and in the next half it travels with a speed of 20 km/hr. Calculate the average speed of the whole journey.

**Example 2 **: If Ananya was able to travel 6 km in North in 2 hour in his car. What was her velocity?

**Example 3**: A car travels 20 km in first hour, 40 km in second hour and 30 km in third hour. Calculat the average speed of the train.
