Answer:
2666.67 m
Explanation:
Changing the 8km/s into SI units we 8000m/s.
Speed of a wave = λf where λ is the wavelength and f he frequency of the wave.
v=λf
Therefore making wavelength the subject of the formula we get
λ= v/f
Substituting with the values in the question we get:
λ= (8000m/s)/3Hz
=2666.667 m
