Answer:
Sound travels to me in a speed of about 340m/s. ∴ total distance/ speed = time taken for the sound to reach me. ∴ 117. 7 or 118 secs (approx) = 2mins or 1min 58 secs.
Explanation:
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
