If an athlete can run 100 meters in 10 seconds, why would it be mathematically wrong to say that he ran 10 meters in 1 second? That is impossible.
Well, I mean running 10 meters in 1 second sounds like a superhero feat and hypothetical, but factually isn’t it correct?! What laws of physics can deny or prove it?

The athlete ran at an average speed of 10m/s. During the first second the athlete was clearly averaging less (as they needed to accelerate). During at least some of the other seconds, their average speed was higher.
Why does it sound impossible to you?
Doing that 10m in the first second (from a stationary start) might be completely impossible as there is no acceleration time, but during the race top athletes can manage that - and if you pick the right second, higher.
