PROPORTION

Ratios needed have the unit of %28onTheMap_inches%29%2F%28inRealDistance_miles%29.

You could do it inverted if you prefer, but keep the unit the same on both sides.

%2816%2Amiles%29%2F%280.125%2Ainches%29=%28d%2Amiles%29%2F%282.25%2Ainches%29

16%2F0.125=d%2F2.25---------now solve for d.

Notice the question asks for the ROUND TRIP distance, so you will want to find 2d.
