Flash, Bang, Thwack

You are standing near a target. You see a flash as a gun is fired. Later, you hear the sound of the gun. Finally, you see the target get hit. The delay between these events is determined by the distance of the shooter and the velocity of the bullet. Here, a rifle bullet is used, with a velocity of 150 meters per second. A pistol often has twice that velocity, and an assault rifle four times that speed.
