The speed of sound in dry air is about: Ssound in dry air ≈ [ 331.4 + 0.6 * TC] in meters per second So about 343.6 meters / second. In 10 seconds, that sound (in dry air) would travel about 3400 meters. Moist air has lower density, which decreases the speed of sound roughly by sqrt( density dry air / density wet air)... so it might be a tad closer.

How many seconds do you need to find the miles to the lightning?
-- Count seconds between the flash of lightning and the thunder -- Divide by 5. -- The result is the number of miles between you and the lightning
This is a delay of 5 seconds between the time you see a flash of lightning and hear thunder if the temperature is 20 celsius how far away is the lightning strike?
So, the sound travels at about 340 meters per second. The answer is 340 meters X 5 seconds equals 1700 meters away is the lightning strikes.
The clap of a thunder was heard 4 seconds after the flash of lightning was seen If the air temperature was 28 degree celsius how far was the lightning?
the lightning was 0.8 miles away.
There is a delay of 5 seconds between the time you see a flash of lightning and hear the thunder?
the lightning is roughly a mile away
How many seconds does lightning strike?
A typical lightning strike lasts for about 0.2 to 0.3 seconds.
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.
How is thunder produced and how far away does the lightning strikes if the thunder is heard 15 seconds after the lightning is seen?
Thunder - is the result of a lightning flash. The flash causes the surrounding air to move away from the source at 300 metres/second. An approximate calculation for the relationship between the lightning flash to hearing the thunder, is 5 seconds per mile.
