Answer #1

Let the height of the cliff be

First, find the time taken by stone to strike the water

Use formula

-----------------

Speed = Distance/time

Time = Distance/speed

------------------

Total time = Time taken by the stone to strike the water + Time taken by the splash sound to travel to the top of the cliff

Multiply all terms with 343

Solve the quadratic equation using a calculator

Note: Please note that the solution is not

Square the value.
