It's difficult to tell since i have serious doubts Kishimoto was trained in the finer points of thermodynamics. Most of it seems to work that way, simply because it looks cool.

If you do some back-of-the-envelope calculations however, i easily end up with 3000m/s speeds for mid-range ninjas. To bend space like Guy did you need to be high-relativistic (close to 300 000 km/s).

Considering, however, that Guy was not the epicenter of a giant thermonuclear explosion, i think it's safe to say that people's speeds are however fast they need to be.
