If the time lag between seeing the flash of lighting and hearing the thunder is 4 seconds how far away is the lighting?

The time lag between seeing the flash of lightning and hearing the thunder corresponds to the distance between you and the lightning strike. To calculate this distance, you can use the fact that sound travels at approximately 343 meters per second in air. So, for a 4-second time lag, the lightning strike is approximately 1372 meters away.
