Lightning quickly heats the air causing it to expand, which produces the
sound of thunder. Sound travels approximately 1 mile in 5 seconds.
Knowing D = r • t (where
D = distance, r
= rate, and t = time), how far
away is a thunderstorm when you notice a 3-second delay between the flash of
lightning and the sound of thunder?
