The distance between two stars is 1.8 × 10^4 light years. What is the distance between the two stars in parsecs? (1 parsec = 3.26 light years)	Choices: A) 8.8 x 10^2 B) 6.6 x 10^2 C) 2.2 x 10^3 D) 5.5 x 10^3 E) 8.8 x 10^4
1.8 × 10^4 ly / (3.26 ly/parsec) = (1.8/3.26) x 10^4 = 0.55 x 10^4 = 5.5 x 10^3 parsec   The answer is 5.5 x 10^3.
