Answer:

x = 3.6 10⁷ m

Step-by-step explanation:

The speed of an electromagnetic wave is constant, in a vacuum its value is c = 3 10⁸ m / s, this speed decreases when entering a material medium,

v = c / n

where n is the refractive index, but in this case the refractive index of air is n = 1.00002. The refractive index of a vacuum is n = 1, so we can assume that the change in velocity is negligible.

For the calculation we can use the relations of the uniform motion

v = x / t

x = v t

let's calculate

x = 3 10⁸ 0.12

x = 3.6 10⁷ m
