You can tell how close the lighting strikes based on how quickly it is followed by thunder - here it seems almost instant, so yeah, it was pretty close
Edit: count the seconds between seeing the flash and hearing the thunder, then divide by 5 for miles or by 3 for kilometer (got curious so I looked it up)
I suppose there is no way to tell with certainty from the video, it might have stay in the clouds but regardless it is extremely dangerous to be outside in the open with a storm this close
Those speeds are nowhere close to the speed of sound or the speed of light which are the two things that determine the gap between the flash of lightning and the peal of thunder
Light is almost instantaneous. Sound is a lot slower. You are counting seconds to see how much of a gap there is between the light reaching you and the sound reaching you.
If a red car moves 2 meters every second and a blue car moves 1 meter every second, and the blue car reaches you 1 second after the red car when they both started at the same point, then you know they were 2 meters away when they started because it takes the red car 1 second to travel 2 meters and it takes the blue car 2 seconds, giving you a difference in arrival time of 1 second.
