If a person clap his hands stands at a distance of 99m from a wall hea – InterviewSolution

1.

If a person clap his hands stands at a distance of 99m from a wall hear the echo after 0.6s, what is the velocity of sound?

Answer»

Distance travelled by the sound

= 2 x 99 = 198 m

time = 0.65

Velocity = \(\frac{Distance}{time}\)

V = 198/0.6

= 330 m/s
