the frequency of a tuning fork is 330Hz.If the velocity if sound in air is 330m/s,then the distance traveled by sound when the fork completes 100 vibrations is

we know the relationship between velocity, frequency and wavelength :
v=lambda ×f
330 = lambda × 330
lambda = 330/330
lambda = 1 m
therefore , the sound travel 1 m in one vibration.
The distance travelled by sound in 100 vibrations = 1 m × 100 = 100 m
hope it helps
