To solve this problem we will use the mathematical definition of the light years in metric terms, from there, through the kinematic equations of motion we will find the distance traveled as a function of the speed in proportion to the elapsed time. Therefore we have to
means Light Year
Then

If we have that

Where,
v = Velocity
x = Displacement
t = Time
We have that
= Speed of light





Therefore will take 14.399 years
