Why does sound travel faster in solids than in gases?                                     

Answer:

                The speed of sound through any medium of bulk modulus \[\kappa \] and density \[\rho \] is given by \[\upsilon =\sqrt{\frac{\kappa }{\rho }}\] The value of the ratio \[\kappa /\rho \] is much higher for solids than that for gases. That is why sound travels faster in solids than in gases.
