The scale of the map from inches to miles is 1 inch : 9 miles
<h3>How to determine the scale of the map from inches to miles?</h3>
The given parameters are:
- The actual distance of the cities apart = 36 miles
- The scale distance of the cities apart = 4 inches
The scale of the map from inches to miles is represented as:
Scale of map = The scale distance of the cities apart : The scale distance of the cities apart
Substitute the known values in the above equation
Scale of map = 4 inches : 36 miles
Divide both sides of the ratio by 4
So, we have:
Scale of map = 4/4 inches : 36/4 miles
Evaluate the quotient
Scale of map = 4/4 inches : 9 miles
Evaluate the quotient
Scale of map = 1 inch : 9 miles
Hence, the scale of the map from inches to miles is 1 inch : 9 miles
