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 \(=\ 330\ \frac{m}{s}\)).

The distance between two points is calculated using the formula.

\(Distance\ =\ \frac{Speed}{Time}\)
\(Distance\ =\ Speed \times Time\)
\(Distance\ =\ \frac{Time}{Speed}\)

Paheli's distance from the lightning spot \(=\) \(m\)
