Distances in space are measured in light-years. The distance from Earth to a star is 4.1 x 10^13
kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 10^12 kilometers)?
To find the distance in light-years, we divide the given distance from Earth to the star, which is 4.1 x 10^13 kilometers, by the conversion factor of 1 light-year = 9.46 × 10^12 kilometers.
So, the distance from Earth to the star in light-years is (4.1 x 10^13 kilometers) / (9.46 × 10^12 kilometers/light-year) = 4.34 light-years. Answer: \boxed{4.34}.
