Answer:
How's the solution buddy ?
Explanation:
Let's assume,
body travels with speed V1 from A point to B point and with speed V2 from point B to C
So, here distances are AB and BC
time=x units
As we know speed=Distance/Time, i.e, it's rate of distance traveled or covered!
Therefore, V1=AB/x and V2=BC/x___(1)
So, AB=V1*x and BC=V2*x____(from_(1))
Hence Av.Speed=Total Distance/Total Time
Therefore Av.Speed=V1*x/2x+V2*x/2x
