    6 m/s

    Explanation:

    The velocity of waves, v is a product of frequency and wavelength expressed as v=fw where v is the velocity, f is frequency and w is wavelength.

    Wavelength is defined as distance between two successive crests or troughs. In this case, the wavelength is 3m

    Substituting 2 Hz for frequency and 3 m for wavelength then the speed of waves will be v=2*3=6 m/s
