Answer:

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

Answer:

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.
