Answer:
Time taken to travel x distance with speed v1 is, t¹ = x/v1.
Time taken to travel next x distance with speed v2 is , t² = x/v2.
Total time t= t¹ +t² =x{( v1+v2)/v1.v2}.
Average velocity= [(x+x)/t]
=2x/x{(v1+v2)/v1.v2}
=2.v1.v2/(v1+v2).

Answer:
2V1V2/V1+V2
Explanation:
average velocity = total displacement / total time
v = s/t
t = s/v
t1 = s/2/v1 (or) s/2V1
t2 = s/2/v2 (or) s/2V2
average velocity = S/2+S/2/ S/2V1+S/2V2
WE WILL TAKE COMMON S/2
S/2(1+1)/S/2(1/V1+1/V2)
S/2 GETS CANCELLED
2/1/V1+1/V2
TAKE L.C.M V1,V2
2/V1+V2/V1V2
=> 2V1V2/V1+V2
