The distances in space are measured in light-years. The distance from Earth to a star is 5.9 × 10^13 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 10^12 kilometers)?

 1.61 light-years
 3.56 light-years
 5.58 light-years
 6.23 light-years

3mar · Answer

$$1 light year=9.46*10^{12}km$$
then
$$?light year=5.9*10^{13}km$$
So
$$?=5.9*10^{13}/(9.46*10^{12})$$ 
=16.81 light years
