## What is Average Velocity?

It is the total distance travelled in a particular diection divided by total time taken

We can say that

Average Velocity = Total Displacement/Total Time Taken

AVERAGE SPEED FORMULA

Average Speed = Total Distance/Total Time Taken

AVERAGE VELOCITY FORMULA

Average Velocity =Total Displacement/Total Time Taken
