How far is lightning when you hear thunder?

Answer 1

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.

Answer 2

when you hear lightning you count by thousands e.g 1000, 2000 3000...

and wwhen you hear the thunder you stop and whaterver 1000 you're up to you add kilometres

hope i've helped:>

Answer 3

Thunder can be heard up to about 10 miles away, but it can be much closer. One way to figure the distance is to measure the time between seeing the lightning and hearing the thunder. Divide the number of seconds by five and to get the approximate distance in miles.

Answer 4

A lightning strike is about 1,100 feet away if you hear the thunder one second after the lightning flash. The distance varies somewhat with temperature, air pressure, and other environmental conditions.

Answer 5

You can hear lightining from MILES away. I coulden't say how much!

Answer 6

Right when you hear thunder start counting by seconds. When you see lightning, whatever number you got to is how many miles away the storm is.

Answer 7

Usually thunder is inaudible at a distance of about 10 miles (16 kilometers).
