its said 3 seconds to a KM but in real life this can be affected by atmospheric conditions ie.. wind, dust, rain etc... Sometimes strikes dont produce a definate beginning and end so it is hard to judge. I have also encountered thunderless lightning, where the sound does not reach the observer at all, due to various reasons I have no idea on
