Question

if any objects travel half of its distance with speed velocity and remaining with speed velocity 2. then find the average speed of the object

Answer 1

The Simplest formula for determining the Average speed in this case is:
$v = \frac{2 v_{1} v_{2} }{ v_{1} + v_{2} }$
where v1 is velocity of the first Half
and v2 is the velocity in the second Half of the journey
