○=> Correct option :
[tex]\color{plum}\tt\bold{(C) \: 500 \: mi}[/tex]
○=> Steps to derive correct option :
Scale of a map :
=> 1 inch = 125 miles
Distance between two cities in map = 4 inches
Actual distance between the two cities :
[tex] =\tt 125 \times 4[/tex]
[tex] =\color{plum}\tt 500 \: miles[/tex]
Thus, the actual distance between the two cities = 500 miles
Therefore, the correct option is (C) 500 mi
