    Answer:

    1000 Hz

    Explanation:

    The frequency would be 1000 Hz.

    The frequency, wavelength, and speed of a wave are related by the equation:

    v = fλ ………………(1)

    where v = speed of the wave, f = frequency of the wave, and λ = wavelength of the wave.

    Making f the subject of the formula:

    f = v/λ…………………….(2)

    Also, speed (v) = distance/time.

    From the question, distance = 900 m, time = 3.0 s

    Hence, v = 900/3.0 = 300 m/s

    Substitute v = 300 and λ = 0.3  into equation (2):

    f = 300/0.3 = 1000 Hz
