Answer 2

Dear Student,

◆ Answer -

Distance between person and cliff = 865 m

● Explaination -

Time taken to hear echo is calculated by -

Time taken = 2 × distance between person and cliff / speed of sound

Distance between person and cliff = time taken × speed of sound /2

Distance between person and cliff = 5 × 346 / 2

Distance between person and cliff = 865 m

Therefore, distance of cliff from person is 865 m.

Thanks dear. Hope this helps you...
