How long does it take for sound to travel around the world ?

Answer 1

I hope you don't meant the gunshot a the battle of Lexington ("the shot heard round the world").

Sound: Earth quake tremors are heard round the world, but they go thru the Earth.

If it were possible for a sound in air to travel around the world , it would have to travel in multlple paths, as no straight path exists. Assuming the paths available made the distance twice the circumference of the Earth, then

time= 2*24,000miles/.2mile/sec
= 48000/.2 seconds= about 240,000 seconds or about 240000/3600 hours= 67 hours.
