Question

Quizplus · Accepted Answer

The scale factor for the map to real-life conversion is found by dividing the real-life distance by the map distance for the shortest side: 90 km / 9.0 cm = 10 km/cm. The longest side on the map is 15 cm, so the longest real-life distance is 15 cm * 10 km/cm = 150 km.
