Question

give a real life situation which shows the body posses some average speed but its averagr velocity is 0

Answer 1

see average velocity can be negative in opposite direction but speed is never negative. example you are going in car speed and velocity are same but in car when you take reverse in car speed is positive but velocity is negative so if any motion is opposite to original motion then velocity is negative but speed is positive. speed is indicated by speedometre 

Answer 2

HEY , HERE'S THE ANSWER ⏬

We know that ,
Velocity =

$\frac{displacement}{time}$

and

$speed = \frac{distance}{time}$

✔️Therefore , A real life situation which shows the body posses some average speed but it's average velocity is zero is that a "FAN"

⏺️REASON : When we switch on the fan , it starts with an average speed but it is placed in a fixed position . So , no displacement occurs at that time .
