Answer:
Average Velocity = 2V1V2/(V1+V2)
Explanation:
Let the total distance be x.
So time taken to cover first half =(x/2)/v1=x/(2v1)
Time taken to cover second half=(x/2)/v2=x/(2v2)
Now average velocity=Total Distance/Total time = x/((x/2v1)+(x/2v2)) = 2v1v2/v1+v2
Answer:
2*V1*V2
V1 + V2
Explanation:
Average velocity = Total Distance ------1
Total Time taken
let distance be x
Velocity = Distance -----2
Time
Using 2:
V1 = x => t1 = x
t1 V1
V2 = x => t2 = x
t2 V2
Using 1
Vnet = 2x.
x + x
V1 V2
on solving.....u will get the required answer.....
