Question

Sound produced by a thunderstorm is heard $10s$ after the lightning is seen. Calculate the approximate distance of the thunder cloud. (Given the speed of sound = $340m{s}^{-1}$)

Answer 1

Step 1: Given data

Speed $v=340m{s}^{-1}$

Time $t=10s$

Step 2: To find out the distance

As we know,

$Dis\tan ce\left(d\right)=speed\left(v\right)\times time\left(t\right)$

$d=340\times 10$

$\Rightarrow d=3400m=3.4km$.

Thus, the approximate distance of the thundercloud is $3.4Kms$.
