Question

if for half time the body moves with velocity of 10 m/s  and remaining half time it moves with velocity of 20 m/s then average velocity of the body is 

10 m/s

15 m/s

25 m/s

20 m/s

​

Answer 1

Answer:

15 m/s

Explanation:

Average velocity = total dist /total time

So, (10×t/2 + 20×t/2)/t

= 15 m/s
