The general rule is to divide the number of seconds by 3 to estimate the distance in kilometers between you and the lightning bolt. This is because sound travels at a speed of approximately 340 meters per second in dry air, which is about 1 kilometer every 3 seconds. Therefore, if you divide the number of seconds by 3, you can estimate roughly how far away the lightning struck.
