Speed of sound in air = 344 m/s
Distance of obstacle from source of sound = 17.2 m
Since, The minimum distance of obstacle from sound source is 17.2 which is half of the total distance covered by sound from point of generation to reflecting surface and back.
Calculation will be 344 m/s * time
= 34.4 Or time
= 0.1 s of sound in air
= 344 m/s
Distance of obstacle from source of sound = 17.2 m
