Determine the distance at which the lighting struck
First, we need to determine the speed at which the lighting struck because the peed of sound varies with temperature.
At about 28C, the speed of sound is 346m/s
So, we have the following:
Distance is calculated as thus:
Divide by 1000 to get distance equivalent in kilometers
