Respuesta :

Given:

The distance from the earth to Proxima Centauri is

[tex]d=\text{ 4.01}\times10^{13}\text{ km}[/tex]

Also,

[tex]1\text{ light year = 9.46 }\times10^{12}\text{ km}[/tex]

To find the distance between the earth and Proxima Centauri in light-years.

Explanation:

The distance from the Earth to the Proxima Centauri is

[tex]\begin{gathered} d=\frac{4.01\times10^{13}}{9.46\times10^{12}} \\ =\text{ 4.24 light years} \end{gathered}[/tex]

Thus, the correct option is B
