The speed of sound actually varies depending on the medium through which the sound is traveling. The speed of sound varies directly with the number of degrees of freedom of each molecule in the gas and varies inversely with the molar mass of the gas.
The speed of sound in air is approximately 331.5 meters per second or 741.5 mph.

In general, the speed of sound c is given by
c = sqrt(C/ρ )
where
C is a coefficient of stiffness
ρ is the density
Thus the speed of sound increases with the stiffness of the material, and decreases with the density.
The speed of a sound wave in air depends upon the properties of the air, namely the temperature and the pressure. The pressure of air (like any gas) will effect the mass density of the air (an inertial property) and the temperature will effect the strength of the particle interactions (an elastic property). At normal atmospheric pressure, the temperature dependence of the speed of a sound wave through air is approximated by the following equation:
v = 331 m/s + (0.6 m/s/C)*T
where T is the temperature of the air in degrees Celsius. Using this equation is used to determine the speed of a sound wave in air at a temperature of 20 degrees Celsius yields the following solution.
v = 331 m/s + (0.6 m/s/C)*T
v = 331 m/s + (0.6 m/s/C)*20 C
v = 331 m/s + 12 m/s
v = 343 m/s

The speed at which sound travels which can be different speeds according to what medium it is traveling through. Usually it is air, but could be different gases, liquids, solids.
