Answer 1

To solve for the actual measurement based on the scale factor specified in the map, follow this example:

Model measurement: 55.7 cm
Actual measurement: 265.4 m

Scale factor = model measurement / actual measurement

Scale factor = 55.7 cm / 265.4 m
Scale factor = 0.2098 cm/m or 4.76 m/cm
