PS - ALthough you're getting the full 3 this time, it's asked that you give an explanation for the answer also. https://forums.windrivers.com/images.../2005/03/1.gif
Add 2 to the first number. Subtract 1 from the second number.Quote:

Without the aid of anyone or anything, how would you estimate the distance of a thunderstorm, from your current position?
__________
Sound travels through air at "the speed of sound." Officially, the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit). At a temperature like 28 degrees C (82 degrees F), the speed is 346 meters per second.
As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck. If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away.
Visualize the lightning, count until you hear thunder. Every 5 seconds is a mile...Quote:

Man, got tied up on a call and got beat out by Ya_Know again! :sad:
Or, like one of the local yokels had said, "I heard the flash, and saw the boom!" :DQuote:

speed of sound is roughly 1100 feet per second, or roughly 770 MPH. At 5280 feet in a mile, that averages out to just shy of 5 seconds for a sound to travel a full mile.Quote:

Another point for the explanation, BTW.
Out of curiosity, had you received any points before today? Your name wasn't on the list when I modified it earlier.
