Speed of sound=340 m/s
Speed of light= 3 x 10^8 m/s
Can you explain how to do this, please?

Well.
How fast does sound travel in three seconds?
3x 340 m/s = 1020 m. I thought that was
a little fast, but I could be wrong.
Light travels way faster than that, so you pretty
much see the lightning right when it happens.
So the event occurs 1020 meters away.

Make the assumption that you see the light almost instantaneously then you use the speed of sound to estimate the distance to the strike so:
340 m/s times 3 s gives 1020 meters. So the lightning struck just over a kilometer away.
Hope this helps!

3 miles. That's what I have been told. You count the seconds between the lightning strike and the thunderclap.....number of seconds = number of miles. Simple. Hope that helped.

The speed of light is too high to affect the result, so the distance is number of seconds times the speed of sound.
