  • The speed of sound varies based upon the density of the air. Yet, given normal air quality the average speed of sound is 761 miles per hour or 1,100 feet per second. If a mile is 5,280 feet, than the sound needs to travel 20,064 feet (the equivalent of 2.8 miles times 5,280 feet). At 1,100 feet per second, it would take sound 18.24 seconds (20,064 divided by 1100) to travel 2.8 miles.
