Answer: For metric-system conversions, follow this method: Sound travels at about 340 m/s, so multiply the number of seconds you counted by 340, and you'll know how many meters away lightning struck. A three-second count, then, would place the lightning strike about 1,020 m away, or roughly 1 km. Originally published on Live Science.

Answer:

Explanation:

With speed of light at 3x10^8m/s, the lightning can be assumed to reach instantly.

If the sound of thunder from that lightning strike arrives 6 seconds later, the sound has traveled:

speed of sound at 340 m/s x 6 s

= 2040 m

~ 2 km
