As we know, the velocity of sound is given by:
Velocity = frequency*wavelength.(I)
In this question,
Frequency = 320Hz
Wavelength= 0.25m
Therefore putting values in equation I
Velocity= 320*0.25 = 80m/sec
Now we know that
Distance=Speed*Time
Time = 10sec
Distance travelled by sound = 80m/sec*10sec = 800m
