Question

A man fires a rifle in front of a cliff and hear the Echo after 3 seconds. Calculate the distance of man from the Cliff if velocity of sound in air is 340 m/s. ​

Answer 1

Answer:

Explanation:

Given

V=340

D=?

T=2sec

V=2d/t

340=2*d/2

340m=d

Hope it helps u

Answer 2

ANSWER

Given,

speed of sound in air, v = 340m/s

time taken to hear echo, t = 3s

As we know that distance,s = speed×time

= 340×3 = 1020m

As in 3 seconds sound has to travel twice distance between man and the Cliff.

So,

distance between man and Cliff is

$= \frac{s}{2}$

$= \frac{1020}{2}$

= 510 m
