Sound travels by impacting air, the air then travels and the sound you hear is the impact of the air on your ear drum. Frequency is the rate at which air is impacted at the source and pitch refers to the size of the impact. Sound travels at just over 300ms-1 so it's not hard to travel faster than sound, sonic booms are created when something exceeds the speed of sound i.e. A concorde or the crack of a whip.
