Answer:
FLASH TO BANG RULE.
Explanation:
The “Flash-To-Bang” theory measures the time from when you see lightning to the time you hear the associated thunder. A measure of 5 seconds from Flash-To-Bang means lightning is one mile (1.6km) away. Ten seconds equals 2 miles (3.2km); 15 seconds equals 3 miles(4.8km).
Light travels faster than sound, so lightning will be seen before hearing it (the thunder is the sound of the lightning strike).
The speed of sound travels at around 340m/s, multiplied by 3 is about 1kilometer. So the number of seconds divided by 3 is how many kilometers away the lightning struck is.
The number of miles away a thunder struck is, can be calculated by dividing the seconds by 5.
