Length in Inches  	  1 1/4  	  1 1/2  	  1 3/4  	  2 1/4  	  2 1/2  	  2 3/4  
  Length in Miles  	  30  	  36  	  42  	  54  	  60  	  66

$\text{difference in inches=difference in miles}\
1\cfrac{1}{2}-1\cfrac{1}{4}~~inches=36-30~~miles\
1+\dfrac{1}{2}-1-\dfrac{1}{4}~~inches=6~~miles\
\dfrac{1}{2}~~inches=6~~miles$
