Answer:

810.37 m/s

Explanation:

s = Displacement = 5 m

v_a = Speed of sound in air = 343 m/s

Time taken to travel the distance

t'=\dfrac{s}{v_a}\\\Rightarrow t'=\dfrac{5}{343}\\\Rightarrow t'=0.01457\ s

Time for the sound in metal

t=0.01457-8.4\times 10^{-3}=0.00617\ s

Speed of sound is given by

v=\dfrac{s}{t}\\\Rightarrow v=\dfrac{5}{0.00617}\\\Rightarrow v=810.37277\ m/s

The speed of sound in the metal is 810.37 m/s
