A rough estimate can be made by counting the number of seconds from the lightning flash until the thunder peal, then dividing the number of seconds by five to get the distance, in miles.
As the speed of light is so huge, you can consider the time you see the flash as equal to the time it actually occurred. Sound travels at 1100 ft/sec, so it travels about a mile in five seconds. The difference in time between seeing the event and hearing it can be used to determine its distance from you.

The lightning happened approximately one mile away for each five seconds it takes for the thunder to be heard.

Estimate the number of seconds that elapse until the thunder is heard. Then multiply by the speed of sound (1128 ft/sec).

When you see the lightning, count one-onethousand, two-onethousand, three-onethousand, etc until you hear the thunder, if you stop on four-onethousand than the lightning struck 4 miles away.

ax=vt
v=300000km/s
t= time that light is traveled in second
x=distance in me tr
with above mention formula we can measure the distance which light is occurs
