Sound travels at different speeds depending on the pressure of the air. That's why the mach scale was created - otherwise people could just use MPH or KPH - the rules of flying change when you break the sound barrier, and the laws on where you can fly do too, (the Concorde can only go supersonic when it's out to sea - that's why you never hear the sonic boom. (Another reason is they were discontinued, but I think they're coming back)).

Depends on what you're mesurering the speed in. Sound travels faster through a liquid than air, and faster through solids than liquid.
In a vacumm, the speed of sound is zero.
In air at sea level, roughly 761mph
In air between 11,000 and 20,000m, roughly 660. An aircraft traveling faster than this is travelling supersonically, after first creating a sonic boom.

The speed of sound in dry air at STP is 331 m/s

the speed of sound is at least 800 mph and is the speed of a bullet when it leaves the gun barrel

depends on termperature. but at STP( 1 atm pressure and 0 degrees Celcius) its 331 m/s

Depends on what the sound is traveling in - air, 1,087 fps; helium, 2,924 fps.
