We will have the following:
First, we know that 1 miles has 5280 feet, so 10 miles will have 52800 feet.
Then we will calculate how 15 feet would be represented:
[tex]x=\frac{2in\cdot15ft}{52800ft}\Rightarrow x=\frac{1}{1760}in\Rightarrow x\approx0.000568in[/tex]So, approximately 0.000568 inches would represent 15 feet.
