The height of the cliff is 510 m

The given parameters include;

  • time of motion, t = 3
  • speed of sound, v = 340 m/s

The height of the cliff is calculated from the principle of echo;

The sound velocity is the ratio of the double distance and time of motion when the sound is heard. This distance is equal to the height of the cliff.

Mathematically, it is written as follows;

[tex]velocity = \frac{2 \times \ distance }{time } \\\\2d = velocity \times time\\\\d = \frac{velocity \times time}{2} \\\\d = \frac{340 \times 3}{2} \\\\d = 510 \ m[/tex]

Thus, the height of the cliff is 510 m
