The scale on a map of Roswell, New Mexico is 1 inch : 0.51 miles. If two buildings in Roswell are 2.8 miles apart in real life, then to the nearest tenth of inch, how far apart are they on the map?
Enter your answer as a decimal rounded to the nearest tenth, without unit
+486 $\frac{1in}{0.51mi}=\frac{x}{2.8mi}$
$0.51x=2.8(1)$
$x=\frac{2.8}{0.51}$
$x=$about$\boxed{5.5}$
