<span>Length that is distance s = 4.00m
 Speed of sound in air V = 343 m/s
 Time for metal = 11.0ms = 0.011
 Calculating the time t = s / V = 4 / 343 = 0.01166s
 Time for the sound in the metal = 0.01166 - 0.011 = 0.00066 = 6.6 x 10^-4s Speed of sound in metal Vm = 4 / 6.6 x 10^-4 = 6.060 x 10^3 m/s</span>
