Homework Help: Introduction to Physical Science

Posted by Tyrone on Thursday, August 22, 2013 at 4:02pm.

A rule of thumb for estimating the distance in kilometers between an observer and a lightning stroke is to divide the number of seconds in the interval between the flash and the sound by 3. Discuss whether or not this rule is correct.

I say it is correct because the speed of light is faster than the speed of sound, sound has a delay. (Am I heading in the right direction with this answer.)
