    The answer is 1020 meters.

    Explanation:

    The values given by the problem are:

    1. T = The falling time of the rock [Seconds]

    2. H=The sound velocity constant [meter/second]

    The Velocity normal formula is

    V=H/T

    340=H/3

    340*3=H

    This solution considers the physic of the traveling wave sound but not really the rock falling problem, because the problem ask for the height of the cliff not even more.
