Speeding

speed is a bullet compared to the speed of sound?

Let's say two men are10-15 feet away from each other. A man has a gun. The man with the gun shoots the other man. "The other man has enough time to leave the direction of the bullet from the moment he heard the shot?

It depends. 1. some are sub sonic bullets are moving slower than sound. So, technically, the man who listens before he was hit. 2. Others are supersonic bullets to hit the man before he could hear. 3. Even subsonic bullets are moving too fast to dodge a 10-15 yard passing sound. Weather human Reactine and speed is too slow. Trivia in the Trigun anime 'hero' dodging bullets by looking at the finger on the trigger and guess when the gun went off. (And he is faster than a normal human.)
