Here is a good tool to use to measure how far away a thunderstorm is.
Assume that seeing the lightning is instantaneous, as light travels very quickly.
The speed of sound in air is about 1 mile every 5 seconds. So count the seconds between seeing the lighning and hearing the thunder. Every 5 seconds is one mile.

Because light travels faster than sound, so even though the light and sound originate from the same point at the same time the light travels much faster (3x10^8 m/s) than the sound (~330m/s) and so you see the explosion before you hear it. It is much the same for thunder and lightning if you think about it!

Light travels much faster than sound, so you see them almost instantly, but if they're far away the sound may take a few seconds longer to reach your ears.

depends how far away you are. speed of light is much faster than speed of sound so the light gets to your eyes before the sound gets to your ears. just like when you see lightning before you hear thunder.

It is the same as thunder and lightening.
The light and the sound are produced at the same time, but sound travels slower.

because light travels faster than sound. you see the light from the explosion almost immediately, but the sound from the blast takes longer to reach your ears.

Because the speed of light is 299792458 m / s (186282.397 miles per SECOND) and the speed of sound is a meager 340.29 m / s (769 miles per HOUR).

Light travels at 186000 mi/sec while sound travels at 1100 feet per sec.....George
