Question

A person standing on a hill fires a gun and hears the echo after 1.6 sec Find the distance between a person and the hill (speed of sound in air 340m/s)​

Answer 1

Answer:

Suppose d is the total distance between two cliffs and x is the distance between the man and one cliff.

2x=v×t

v×t

340×1.5

=255 m

2(d−x)=v×t

(d−x)=

340×3.5

(d−x)=595 m

d=595+x

=595+255

=850 m
