Question

Distances in space are measured in light-years. The distance from Earth to a star is 6.8 × 1013 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 1012 kilometers)? (5 points)   2.66 light-years 7.18 light-years 7.74 light-years 9.46 light-years

Answer 1

The distance from Earth to the star is 7.18 light-years

Answer 2

I light year = 9.46 x 10¹² km

-------------------------------------------------------------------------------------
Find the number of light years
-------------------------------------------------------------------------------------


`\text {Number of light years = } (6.8 * 10^(13))/(9.46 * 10^(12))`


`\text {Number of light years = } 7.18`

-------------------------------------------------------------------------------------
Answer: The distance from Earth to the star is 7.18 light-years.
