The distance between two stars is 1.8 × 10^7 light years. What is the distance between the two stars in parsecs? (1 parsec = 3.26 light years)
Pick:	A) 1.1 x 10^2	B) 2.2 x 10^3	C) 3.3 x 10^4	D) 4.4 x 10^5	E) 5.5 x 10^6
1.8 × 10^7 ly / (3.26 ly/parsec) = (1.8/3.26) x 10^7 = 0.55 x 10^7 = 5.5 x 10^6 parsec   The answer is 5.5 x 10^6.
