Question

A man standing between two parallel hills, claps his hand and hears successive echoes at regular intervals of 11s If velocity of sound is $340 m s to the power of negative 1 end exponent comma$ then the distance between the hills is

100m
170m
510m
340m

The correct answer is: 510m

Let the man $M$ be at a distance $x$ from hill $H subscript 1 end subscript$ and $y$ from hill $H subscript 2 end subscript$ as shown in figure. Let $y greater than x.$

The time interval between the original sound and echoes from $H subscript 1 end subscript$ and $H subscript 2 end subscript$ will be respectively
$t subscript 1 end subscript equals fraction numerator 2 x over denominator v end fraction$ and $t subscript 2 end subscript equals fraction numerator 2 y over denominator v end fraction$
where $v$ is the velocity of sound
The distance between the hills is
$x plus y equals fraction numerator v over denominator 2 end fraction open parentheses t subscript 1 end subscript plus t subscript 2 end subscript close parentheses equals fraction numerator 340 over denominator 2 end fraction open square brackets 1 plus 2 close square brackets equals 510 blank m$
