# 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).

Given: Time period = 5s

Speed of sound = 330 m/s

To calculate distance, we will apply the formula given below:

Distance = Speed × time

Distance = 330 m/s × 5s

Distance = 1650 m

Distance = 1.65 km ( 1km = 1000m)

Thus, she is standing at 1.65 km.
