Question

a man standing two parallel Cliffs fires a gun he hears of first echo after 1.5 second and the next echo 2.5 second . what is the distance between the Cliff . Take the speed of sound in the air at 340 per second .​

Answer 1

Step-by-step explanation:

Time taken by first echo: 1.5s

Speed of sound :340m/s

distance:?

2d=v×t

2d=340×1.5

2d=510

d=510/2

d=255m

Therefore,the distance between the cliffs is 255m.
