A map shows that city A is 65 miles north of city B. A ruler shows that the cities are 3 inches apart on the map. How many actual miles are represented by each inch on the map

1 in is represented as 21.6667 miles

Explanation:

Data provided in the question:

Distance between the city A and the city B = 65 miles

Distance measured by the scale on the map between the city A and the city B = 3 inches

Thus,

3 inches is represented as 65 miles

Thus, applying the unitary method

1 in is represented as 65/3 miles

or

1 in is represented as 21.6667 miles
