    Answer: 3 m/s

    Explanation:

    The wavespeed of a wave is the distance covered by the wave in one second. It is measured in metre per second, and represented by the symbol V.

    Wavespeed (V) = Frequency F x wavelength λ

    V = F λ

    In this case,

    wavelength (λ) = 1 m

    Frequency = 3 Hz.

    Hence, V = F λ

    V = 1m x 3Hz

    V = 3 m/s

    Thus, the wavespeed is 3m/s
