How far away is lightning?
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you’ll get the distance in miles to the lightning:
5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close
. Keep in mind that you should be in a safe place while counting.
What distance will light travel in one second?
