Answer:
[tex]\frac{1}{5}\frac{in}{miles}[/tex]
Step-by-step explanation:
we know that
The original scale of the map is
[tex]\frac{2}{30}\frac{in}{miles}=\frac{1}{15}\frac{in}{miles}[/tex]
If the map is enlarged to 3 times its size
then
the new scale will be
[tex]\frac{2*3}{30}\frac{in}{miles}=\frac{6}{30}=\frac{1}{5}\frac{in}{miles}[/tex]
