It's not nonsense, but remember that speed is absolute so we just find the change in distance between A and B for a very small amount of time.

If you want a test without an abstract definition of length, then the Doppler effect is a way.

> speed is absolute

That's some thing to say...

What I meant was that speed is the magnitude of velocity, rather than a vector.
