It is important to note that sound speed in air is determined by the air itself. It is not dependent upon the sound’s amplitude, frequency or wavelength. To calculate the speed of sound in dry air at sea level, use the following formula:
V = 331.4 + 0.6Tc
the speed of light in a vacuum is 299,792,458 meters per second or 186,000 miles per second (669,600,000 mph), which is roughly 870,000 times faster than the speed of sound. The difference between the speed of light and the speed of sound is why you see lightening before you hear it (unless you are struck by it, in which case it may be simultaneous!).
As a comparison with sound in other mediums, the speed of sound in helium at 0°C is approximately 972 meters per second (m/s), or around 3 times as fast as in air. Sounds travels even faster in liquids and solids because of their greater density (although standard measurement is slightly more complicated because of it is effected by the shape of the material and also the fact that both longitudinal and transverse waves may propagate in solids). Sound in 20° C water travels an average of 1482 m/s, while sound in aluminum travels at 6420 m/s. Modern navies depends heavily on being able to predict the speed of sound in varying water conditions for their SONAR echo-location systems.

The speed of sound in air is:
331 m/s, or 761 mph.
It is different for other mediums with different densities, such as water (where it's very high), or helium (which is why your voice gets a funky pitch).

The speed of sound is 763.66519526 Miles per hour. I can only assume that's what you're asking.

Lets guess who's going to get the 10 points for the best answer shall we?? Chris G with his thoughtful and considered essay, or #1 hot chick with the come on.

fast means the speed.
therefore, the of sound is 3.8 x 10*8 m/s

the speed of sound through the standard atmosphere is 761 mph (1223 km/h) at sea level...thats all

properly.... many talk with motorbikes (motorcycles) as Iron horses. i might want to have a not user-friendly time choosing between a short motorcycle and a stay, quick horse. automobiles are too confining.

I believe it's 776 mph at STP at sea level.

That would be 761 mph.

I think HOT CHICK is right
