Lightning and thunder occur almost exactly the same time. Yet you see a flash of lightning before you hear the crack of thunder. Light travels nearly a million times faster than sound. The sound of thunder travels one mile (1.6 kilometers) in five seconds. The next time you see a lightning flash, count the seconds until you hear thunder. Divide that number by five. That's how many miles you are away from a thunderstorm.
