How many miles away is the lightning when you count 40 sec from when you saw the lightning until when you hard the thunder?
What I do know is it takes 5 seconds for the sound waves to travel 1 mile.So, if it's 5 seconds per mile, take 40 seconds and divide by 5 and the answer is 8 miles. That means if you count 40 seconds and hear the thunder, the flash was 8 miles away.One more thing, every second, the sound travels .2 miles.
How can you estimate how far away the lightning strike will be?
By listening for the thunder. When you see a prominent lightning strike, start counting "one thousand one, one thousand two", etc. Each of those is about one second. There are five seconds in every mile (sound travels 1/5th of a mile per second). If you count to fifteen, the lightning strike is three miles away. Lightning and thunder occur at the same instant when the lightning strike is very close to you, and the thunder will sound more like a cymbal crash.
What is a simple way to estimate how far away lightning?
First, watch for lightning. The second it hits the ground, starts counting in seconds. Stop when you hear thunder. divide the seconds by 5 to get how many miles away the lightning is. For kilometers, divide the seconds by 3.
How far is lightning when you hear thunder?
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.
How do you estimate how far lightning is away from you?
To estimate your distance from a thunderstorm count the number of seconds between a flash of lightning and the next clap of thunder. Divide your answer by 5. See the related link below.
How do you tell how far away a storm is?
To tell how far away a storm is note the seconds between the appearance of lightning and the sound of thunder. Every second between lightning and thunder represents one mile.
What is the distance of lightning if you a thunder a minute ago?
Count each second when you see Lightning, until when you hear Thunder, divide it by 3, and for example 60 divided by 3 makes 20 right, so that means that it is 20 miles away, so that's your answer, Thunder that is heard one minute after the Lightning is 20 miles away.
How far away is a thunderstorm if you SEE a flash of lightning and then HEAR thunder 10 seconds later?
When lightning occurs and creates thunder you see the lightning immediately because light travels so fast (abot 186,000 miles per second). But sound travels much slower so you don't hear the thunder until several seconds after it occurs. I believe the approximate rule that is used is sound travels about 1 mile in 5 seconds. So if it is 15 seconds before you hear the thunder then the storm is about 3 miles away.

How far away is lighting if heard ten seconds later?
sound travels at 334 metres per second, so 3.34 kilometres away

How much time does it take thunder to get to you from a lightning strike 5 miles away?
About 25 seconds. It's closer to 23, but 5 seconds per mile is the general rule of thumb.
Is it true that you can use thunder to tell how far away a storm?
You can generally determine how far away you are from the place of origin by counting 1 one-hundred, 2 one hundred, etc until you hear thunder and divide that number by two. That is how many miles away you are.
What is a common indicator of thunderstorm?
Thunder and lightning, sky darkens, winds increase. A better long distance warning is crackily static on an AM radio. You can only hear thunder about 8 miles away, but the static can be heard about 40 miles away from the storm.
