Question

A body covers one-third of the distance with a velocity V1 the second one-third of the distance with a velocity v2 and the remaining distance with a velocity V3. The average velocity is :​

Answer 1

Answer:

hey buddy...

hope this helps..

Answer 2

Answer:

average speed = total distance covered /total time taken

let the total distance =3x

time taken to cover first one third (x) = t1 = x/v1

time taken to cover second one third =t2= x/v2

time taken to cover 3rd one third = t3= x/v3

average speed = 3x/(x/v1 +x/v2+x/v3)
