Answer:
[tex]Real\hspace{3}length=165in[/tex]
Step-by-step explanation:
In order to calculate the real length, use scale length multiply the scale factor of it, then divide the scale factor of real length:
[tex]Real\hspace{3}length=(Scale\hspace{3}length)*(Scale\hspace{3}ratio)^{-1}[/tex]
Where:
[tex]Scale\hspace{3}length=2.75in\\Scale\hspace{3}ratio=\frac{1}{60}[/tex]
Therefore:
[tex]Real\hspace{3}length=2.75*\frac{60}{1} =165in[/tex]
