The number of seconds between lightning flash and the following thunderclap may be used to estimate, in kilometers, how far away a storm is. How far way is a storm if 12 seconds elapse between the lightning and the thunderclap?

Step-by-step explanation:

Given the formula,

d = t/3

Where,

d is the distance in kilometers

t is the time elapsed

= 12 seconds

d = 12/3

= 4 km

Option D. 4 kilometers.

4.08 km

Step-by-step explanation:

we must know what is the speed of sound to determine the distance at which the ray originated

The speed at which the sound of lightning travels is approximately 0.340km/s

then

d = 0.340km/s*12 s = 4.08 km
