Sound travels faster in solids than gases. It is because the elasticity of solid is more than that of gases. Solids posses greater density than gases. Though density has effect on the velocity of sound in the medium as follows
$v \propto \frac{1}{{\sqrt \rho }}$
In case of solid, its elasticity far exceeds that of gas so its effect far exceeds the effect of density.
