Question

A man walks with velocity v1 for half the time and with velocity v2 for the
remaining half. Motion is in straight line in one directiorl Find average
velocity and average speed. ​

Answer 1

As motion is in straight line.....

☞︎︎︎ᗪIՏTᗩᑎᑕᗴ = ᗪIՏᑭᒪᗩᑕᗴᗰᗴᑎT.

And time taken is also same.....

So...
ᗩᐯᗴᖇᗩᘜᗴ Տᑭᗴᗴᗪ = ᗩᐯᗴᖇᗩᘜᗴ ᐯᗴᒪOᑕITY

= (v1+v2)/2

Answer 2

Answer:

As motion is in straight line.....

$\longrightarrow\bf \blue{☞︎︎︎ᗪIՏTᗩᑎᑕᗴ = ᗪIՏᑭᒪᗩᑕᗴᗰᗴᑎT.</p><p>}$

And time taken is also same.....

So...

ᗩᐯᗴᖇᗩᘜᗴ Տᑭᗴᗴᗪ = ᗩᐯᗴᖇᗩᘜᗴ ᐯᗴᒪOᑕITY

= (v1+v2)/2
