Question

Geeta heard the sound of lightning after 3 seconds of seeing it. What was the distance of the lightning from her? (the velocity of sound in air is 340m/s) plz I need it quickly plz help me​

Answer 1

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.Jun 25, 2013
