Shinobi are not running at supersonic speed, I don't know when Neji stated that, Jonins can run faster than Chunins that is why Temari reached demon desert in less than two days and it took three days for normal Shinobi, Actually I think you mean Neji stated that Shinobi can defend themselves by hearing the sound the attack is coming from, Shira was able to muffle sound, but even the attacks are not supersonic. We don't know how much fast Shinobi can travel. They are depicted in shadowy swift movement because they are ninjas Kishimoto made them look like that, we cannot compare real world 100 mph to anime depiction. I disagree with a big planet theory but by looking at the map I think we are not shown some continents and some location such as Mount Myōboku, It doesn't look world map to me.
