Question

HELP MEEEE Distances in space are measured in light-years. The distance from Earth to a star is 6.8 × 10^13 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 10^12 kilometers)?

Answer 1

7.188 Ly is the correct answer

Answer 2

≈ 7.188 LY

Explanation:

1 LY = 9.46 * 10¹²
S = 6.8 * 10¹³

S = 6.8 * 10¹³/9.46 * 10¹² ≈ 7.188 LY
