Lightning can be seen at the moment when it occurs. Paheli observes lightning in her area. She hears the sound $5\ s$ after she observed lightning. How far is she from the place where lightning occurs?
$(speed\ of\ sound=330\ m/s)$.

Speed of sound $=330\ m/s$

Time taken by sound to reach $=5\ s$

Therefore, distance traveled by the sound $=speed\times time$

$=330\ m/s\times 5\ s$

$=1650\ m$

Therefore, Paheli is $1650\ m$ far from the place where lighting occurs.
