That's not quite correct logic. Since the average velocity can be zero because it is not always true that the components of velocity have to be greater than zero in a coordinate system.

That is, consider a car that takes a path from point A to point B and back to point A (where point A and B are some distance \(s\) away). Then, the car has an average velocity of zero (as it is back to its starting point), yet the car's speed is \(\frac{2s}{t}>0\).
