Solution
The correct option is C223 miles The gap between two integers is divided into 6 equal parts. Each division on the scale corresponds to 16 mile.
A is −11 divisions from 0 and point B is 5 divisions from 0.
Therefore,
Position of city A=−116 miles
Position of city B=56 miles
Distance between A and B = |Position of A - Position of B|
