Answer:

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.
