had a hard time with this problem, ill fan and and medal

OpenStudy (slickster256):

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

OpenStudy (3mar):

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

16.81 isnt a possible answer

Sorry, @slickster256. It is 6.237 light years, the last choice. It was just calculator error.
