SUMMARY
The problem involves calculating the height of a cliff based on the time it takes for a rock to fall and the sound of it hitting the ocean to travel back. The total time of 3.7 seconds is the sum of the time taken for the rock to fall (trock) and the time taken for the sound to travel back up (tsound). Using the speed of sound at 340 m/s, the equations Ttotal = trock + tsound and distance = Vsound * tsound are essential for solving the problem. The correct approach involves substituting the equations to find the height of the cliff accurately.
