Question 1104091
PROPORTION


Ratios needed have the unit of  {{{(onTheMap_inches)/(inRealDistance_miles)}}}.


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


{{{(16*miles)/(0.125*inches)=(d*miles)/(2.25*inches)}}}


{{{16/0.125=d/2.25}}}---------now solve for d.


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