you see a distant flash of light and then you hear a thunder clap 2 seconds later. the sound of thunder moves at 343 miles per second how far away is the lighting?

when I was younger, the sound of lightning moved at about 340 m/s, so after 2 seconds the lightning would have been 686 metres away.

but with today's lightning, which according to you has its thunder moving at 343 miles per second, who knows what would happen.

686 miles

To determine the distance of the lightning, you can use the speed of sound to calculate the time it took for the sound to reach you. Since sound travels at approximately 343 meters per second (not miles), you can use this information to calculate the distance.

Given that you heard the thunder 2 seconds after seeing the flash, you can multiply the speed of sound by the time it took for the thunder to reach you:

Distance = Speed of Sound × Time

Distance = 343 m/s × 2 s
Distance = 686 meters

Therefore, the lightning is approximately 686 meters away from your location.
