Step-by-step explanation:

the speed of the light is

$v=3*10^8\text{ m/s}$

the time in a year is

$\begin{gathered} t=365\text{ days}*24\text{ hours}*60\text{ minutes}*60\text{ seconds} \\ \end{gathered}$

the distance traveled by the light is

$d=v\text{ t}$

Plugging all the values in the above relation, we get

$\begin{gathered} d=365*24*60*60\text{ s}*3*10^8\text{ m/s} \\ d=946080*10^(10)\text{ m} \end{gathered}$

now convert this into miles.

$1\text{ m=0.000621 miles}$

now the distance is,

$\begin{gathered} d=946080*0.000621*10^(10)\text{ miles} \\ d=587.51*10^(10)\text{ miles} \\ d=\text{ 6 billion miles} \end{gathered}$

Thus, the distance traveled by the light in a year is 6 billion.
