HEYA FRIENDS ❤️❤️❤️
A man runs 100 m in 10 second then turns around and jogs 50 m back calculate his average speed and average velocity.
Plz help

here is ur answer
as speed = distance/time
speed = 100/10
speed = 10 m/ s
but av. speed is algebraic sum of distance divided by time and here only one speed is present, therefore
it will be it's averagespeed
Now, velocity = displacement/ time
velocity = 100 - 50/ 10
velocity = 50/10
velocity = 5 m/s
here also the average velocity is equal to the velocity.
