Mick is making a map for Geography. In order to draw the map, he must create a scale converting the measured inches on the map to actual miles.

Length in Inches 1 1/4 1 1/2 1 3/4 2 1/4 2 1/2 2 3/4
Length in Miles 60 72 84 108 120 132

Use the table above to identify the scale he used for his map.

A. 1 in = 16 miles

B. 1 in = 48 miles

C. 1 in = 24 miles

D. 1 in = 12 miles
