hint ... multiply
Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88 x 1012 miles. Suppose a star is 3.2 x 102 light-years from Earth. In scientific notation, approximately how many miles is it?
A. 1.88 x 1012
B. 5.88 x 1014
C. 3.2 x 1015
D. 1.88 x 1015

3.2 * 10^2 light years * 5.88 * 10^12 miles / light year
= about 18 * 10 ^14 miles = 1.8 * 10^15 miles
so yes D
= about 18 * 10 ^14 miles = 1.8 * 10^15 miles
so yes D
