The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium.
$c = \sqrt{\frac{K}{\rho}}$, where $K$ is the coefficient of stiffness, the bulk modulus (or the modulus of bulk elasticity for gases), and $\rho$ is the density. Also, $c^2 = \frac{\partial p}{\partial \rho}$, where $p$ is the pressure and $\rho$ is the density.
