a rule for estimating the distance in kilometers between an observer and a lightening stroke is to divide the number of sec in the interval between the flash and the thunder by 3.is this rule correct?

Yes, that is correct. 1ofSelby's, c'mon....a km is ~3/5 of a mile.
Mile, 5 sec, km, 3 sec.

This rule is not exactly correct. Sound travels around 1100 feet per second so if it takes five seconds to hear the sound of thunder after seeing the lightening the distance would be 5500 feet or approximately 1 mile. Therefore the better rule is to count the seconds after seeing lightening and dividing by 5 to get the number of miles the storm is from you.
