Harish clapped his hands near a cliff and heard the echo after $4 \mathrm{s}$. Find the distance of the cliff from the harish if the speed of the sound, v is taken as $332{ \mathrm{ms}}^{-1}$ ?

In this question speed of sound is given and also time is given, We know thar formula distance is equal to speed multiply by times putting values and then get fina answer.
According to question given that
Speed of sound, $v=332{ \mathrm{ms}}^{-1}$
Time taken for hearing the echo, $t=4 \mathrm{s}$
Distance travelled by the sound $=v\times t=332{ \mathrm{ms}}^{-1}\times 4 \mathrm{s}=1328 \mathrm{m}$
In $2 \mathrm{s}$ sound has to travel twice the distance between the cliff and the Harish. Hence, the distance between the cliff and the Harish
$=1328 \mathrm{m}/4=332 \mathrm{m}\text{. }$
