Compare Two Maps of the Same Route

A map with more real distance per centimeter draws the same route shorter. Calculate real distance separately for each map before deciding whether they agree.

Worked example

A 600 m route measures 3 cm at 200 m per centimeter, but only 1.5 cm at 400 m per centimeter. Changing scale changes the drawing, not the real route.

Three equal map intervals each represent two hundred meters. Together three centimeters at 1:20,000 represents six hundred meters, or zero point six kilometers. — Use the printed labels, not screen size: a resized diagram is not a ruler. Example scale is 1:20,000.

Two Printed Scales

Map A uses 1 cm = 200 m. Map B uses 1 cm = 400 m. Both depict the same fictional routes. Treat the listed map distances as exact practice values, and use the printed scale labels rather than measuring the diagram on your device.

Question 1 A route is 6 cm on Map A. What is its real length in meters? Answer

Question 2 How many centimeters is that 1200 m route on Map B? Answer

Question 3 A path measures 5 cm on Map B. What is its real length in meters? Answer

Question 4 How many centimeters would the 2000 m path measure on Map A? Answer

Question 5 Which statement correctly compares the maps? Map B makes the real route shorter Map A draws the same route twice as long as Map B The route must change direction when its scale changes
