    1.2 Hz

    Explanation:

    Frequency: This can be defined as the number of cycles completed in one seconds. The unit of frequency is Hertz (Hz)

    From the question above,

    f = N/t ... Equation 1

    Where f = frequency, N = number of wave or cycle completed by Johnny, t = time take to complete the waves.

    Given: N = 12 waves, t = 10 s

    Substitute into equation 1

    f = 12/10

    f = 1.2 Hz
