Question

6. A person moves a distance of 3 km towards east, then
2 km towards north and finally 3 km towards west
and takes a time of 2 hours. Find his average speed
and average velocity. Are the two equal?​

Answer 1

Step-by-step explanation:

so here average speed =

$\frac{total \: distance}{total \: time} = \frac{3 + 2 + 3km}{2h} \\ = \frac{8km}{2hr} = 4km |hr$

average velocity =

$\frac{displacement}{time}$

and displacement =final position -initial position

so

$\frac{displacement}{time} = \frac{2 - 0}{2} = 1km |hr$

no they are not equal
