Hi. The sound travels about 1,000 feet per second, so about 5 seconds is about 1 mile.

The speed of light is so fast, if you can see it, it happens instantaneously.
The speed of sound is approximately 771 miles per hour at 70 degrees farenheit, 774 miles per hour at 75 degrees fareheit, making it about 12.9 miles per minute or 1136 feet per second or about 5 seconds per mile.
So, when you see the flash, count the seconds until you hear the bang. Multiply the number of seconds by 1100, and you'll get a good approximate distance.

count of how many seconds you took you to hear thunder after lightning flashes, then divide it by 5 and that will give you the distance.
