Answer:
The average speed of a body in a certain time interval is the distance covered by the body in that time interval divided by time. So if a particle covers a certain distance s in a time t1 to t2, then the average speed of the body is:
vav = st2–t1
In general, average speed formula is:
Average Speed = Total DistanceTotal Time

Answer:
average speed is the total distance travelled divided by total time taken.
It is useful in cases where the the object moves in non uniform speed.
For eg: a car covered 10 km in the first hour and 30 km in the second hour. find avg speed.
total distance=10km+30km=40km
total time=1hour+1hour
Avg speed=total distance/total time
avg speed=40km/2hours
=20km/hr
