**1. Homework Statement**

In which conditions the average speed equals the Average of the Speeds?

**2. Homework Equations**

Average speed= (Xf-Xo)/(tf-to)

Average of the speeds= (vf+vo)/2

**3. The Attempt at a Solution**

I tried to set up a formula for vf and vo, but it would be false to determine that

vf=xf/tf, because if vf=0, xf=2 and tf=1 ->vf=2/1 which is not 0. I tried also to set

vx=a*t + vo, but I'm getting nowhere. Please help :)

I know that it is the case when there is no acceleration. But I'm trying to figure if there is other cases.
