It is possible to hear an approaching train before you can see it by listening to the sound wave through the track. If the elastic modulus is 2.0 × 1011 N/m2 and the density of steel is 7.8 × 103 kg/m3, approximately how many times faster is the speed of sound in the track than in air? (vair≈ 340 m/s.)
