    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
