Chapter 442, Naruto vs pain after the Chibaku tensei.

The timing is weird, because apparently Pain can form black rods, stick them in clones and jump in the air in the same time it takes him to think a single thought ( "he already had his clones in wait"). Not to mention that apparently Naruto can throw himself faster than he can throw a Rasenshuriken, despite the Rasenshuriken having a 28-ish meter headstart (The Rasenshuriken has already travelled 13 out of 14 rasenshuriken-lengths to Pain, and Pain has time to react).

What's worse is that whereas Naruto's first two clones can cross the distance to Pain in the same fraction it takes Pain to react, his latter clones need two full seconds to get to Pain, rather than the fraction one would expect based upon the earlier attempt.

So all in all, it seems there's not much of a logical timing behind all this. After all, 40km in a second is nearly a percent of the speed of light (result: gargantuan fireball), or 144 000km/h. Which, by the way, is MUCH higher than escape velocity. Furthermore, the 30-40-ish meters the Rasenshuriken crosses would be crossed in a millisecond, whereas Pain needs a full second to dodge both.

Therefore, the 40km in 1 second has to be wrong. At dodging 2 Rasenshuriken in a second (with Rasenshuriken 1 being t=0) it would at best be 40-ish meters in half a second, or 80m/s. That, by the way, is 188km/h. Accounting for the rasenshuriken head-start, i may be off by an order of magnitude, but even that would be significantly lower than 40km/s, and at worse about Mach 2-3(~3km/s)

Lastly in the case of Minato V Raikage, assuming humans see about 60 FPS and that the Raikage covers about 20 meters in that one frame, that's about a similar figure (4000km/h). Considering this and the aforementioned rough Rasenshuriken figures, i would expect this to be about the upper logical limit. The same argument can be extended for just about any shunshin, although in those cases there's a visible blur (suggesting multiple frames can be seen) and the results would be in the same order of magnitude.

Much higher and you get into thermodynamic problems (basically, fireballs). Sonic booms wouldn't be as loud with humans (e.g. a whip breaks the barrier and makes a clear cracking sound but it's not window-shattering). Considering that Genin can already move at 40km/h comfortably (Boruto movie, chasing a panda which can run 40km/h just about) and that many animals can even go faster (e.g. cheetah goes 100km/h for bursts), having expert Ninja go an order of magnitude above that seems reasonable.
