hmm....i think d answer is actually 1914.00211 but of the time taken to sight lightening were to be neglected, its distance would be 1914m... so u don't know how you guys got ur answer when it's not echo sounding.
Myschool this has nothing to do with echo na. So the 2x part of the formula does not apply. It is X instead.
X=VT
X=330×5.8=1914m

The question here is not based on echo. So the formula to be applied is
speed= distance/time
Distance = speed ×time
Distance = 330×5.8
Distance = 1914m
i don't understand why myschool will choose an answer without an explanation and you basically knew it involves formulas
how do you want us to learn?? You fail me without correcting me
