Lightning can be seen the moment 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).

Explanation

The distance between two points is calculated using the given formula.
Distance = Speed ×Time.
Given that the speed of sound in air is 330 meters per second and the time taken is 5 seconds, distance covered can be calculated as follows.
D=330m/s×5s=1650m
Hence, Paheli is at a distance of 1.65 kilometers from the lightning spot..
