Question

A man is standing between two hills he fires a gun and hears two echos one after 0.3 seconds and another after 0.5 seconds. Find the distance between two hills (please include formulas)

Answer 1

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

2x=v×t

1

x=

v×t

340×1.5

=255 m

2(d−x)=v×t

2

(d−x)=

2

v×t

2

(d−x)=

2

v×t

2

(d−x)=

2

340×3.5

(d−x)=595 m

d=595+x

=595+255

=850 m
