The distance between two planets is 4 × 10^6 light years. What is the distance between the two planets, in parsecs? (1 parsec = 3.26 light years)
Pick:
A) 9.3 × 10^5	B) 9.9 × 10^6	C) 9.3 × 10^7	D) 9.9 × 10^7	E) 1.2 × 10^6
4*10^6 light years = 4*10^6/3.26 parsecs.   4/3.26 is a little bit less than 1, something like 0.9, thus 4*10^6/3.26 = ~1.2*10^6.   Answer: 1.2 × 10^6.
