Question

How the average speed is different from speed?

Answer 1

Speed:

1. Speed is defined as the distance (d) covered by a body in unit time (t).
2. Speed can be calculated as,
   $Speed=\frac{Dis\tan ce}{time}$
3. In daily life, we see vehicles can travel at a higher speed when there is no traffic and slow down when there is traffic.
4. In such cases, we use the concept of average speed.

Average speed:

1. Average speed can be calculated as,
   $Averagespeed=\frac{totaldis\tan cecovered}{totaltimetaken}$
2. Unit of speed and average speed is the same i.e., m/s or km/h.
