Answer:
Distance is 825 meter
Explanation:
It took 2 second for the sound to travel from the man to one of the cliff and return back . So time taken to reach the cliff is 1 second Speed of sound is 330 m/s so distance to first cliff from the man is 330 m.
Using the same method as above we can calculate that it took 1.5 s for sound to reach second cliff from the man.
Distance between man and the second cliff is 1.5*330 and that is equal to 495
So the distance between two cliffs are 330+495
That is equal to 825
