    This question is incomplete; here is the complete question:

    Marco is conducting an experiment. He knows the wave that he is working with has a wavelength of 32.4 cm. If he measures the frequency as 3 hertz, which statement about the wave is accurate?

    A. The wave has traveled 32.4 cm in 3 seconds.

    B. The wave has traveled 32.4 cm in 9 seconds.

    C. The wave has traveled 97.2 cm in 3 seconds.

    D. The wave has traveled 97.2 cm in 1 second.

    The answer to this question is D. The wave has traveled 97.2 cm in 1 second.

    Explanation:

    The frequency of a wave, which is in this case 3 hertz, represents the number of waves that go through a point during 1 second. According to this, if the frequency of the wave is 3 hertz this means in 1 second there were 3 waves. Moreover, if you multiply the wavelength (32.4cm) by the frequency (3) you will know the distance the wave traveled in 1 second: 32.4 x 3 =  97.2 cm. This makes option D the correct one as the distance in 1 second was 97.2 cm.
