    Step-by-step explanation:

    This is just a type of problem like finding how long it will take for you to get somewhere. Like in finding how fast you need to go to go to a place that is 60 miles in one hour. All you have to do is divide the distance of the star by the speed of light, and you get the amount of time it will take for the star's light to reach the Earth.
