```										When we travel in a vehicle the speed of the vehicle changes from time  to time depending upon the conditions existing on the road. In such a  situation, the speed is calculated by taking the ratio of the total  distance travelled by the vehicle to the total time taken for the  journey. This is called the average speed.
If an object covers a distance S1 in time t1, distance S2 in time t2 and distance Sn in time tn then the average speed is given by,

When we say that the car travels at an average speed of 60 km/h it  does not mean that the car would be moving with the speed of 60 km/h  throughout the journey. The actual speed of the car may be less than or  greater than the average speed at a particular instant of time.
