Question

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

Answer 1

Step 1: Given data

$Speedofsound=340m{s}^{-1}$

$Time=10s$

Step 2: Formula used

$Dis\tan ce=Speed\times Time$

Step 3: Calculation

$$\begin{gathered} Dis\tan ce=Speed\times Time \\ =340m{s}^{-1}\times 10 \\ =3400m \\ =3.4km \end{gathered}$$

Hence, the distance of the thundercloud is $3.4km$.
