Is it true that if you see lightning and start counting, whatever number you get to when you hear the thunder is how far away the storm is?

it takes sound about five seconds to go a mile, so for every five seconds you count between lightning and thunder, the storm is one mile away. for example, if you count to 25, the storm is five miles away.

Yes, that's true, but I don't think of counting...I just wait in the silence to hear that awful BOOM!
-
Yes, it's supposed to be a relatively accurate measure. You're basically measuring the speed of the light and sound traveling the same distance, taking the difference, and multiplying by the right factor.

That's about right....but hearing thunder is good reason to get out of a pool or off of a golf course, etc.

If you count 1 and 2 and 3, it's supposed to be a fairly acurater measure of how far away the storm is.
