Why is A map is drawn to scale 1cm to 10km. Find the actual distance represented by 54mm?

If the map scale is 1 cm to 10 km, then 1 mm on the map represents 0.1 km in reality (since 1 cm = 10 mm). Therefore, 54 mm on the map is equivalent to 54 mm × 0.1 km/mm = 5.4 km. Thus, the actual distance represented by 54 mm is 5.4 kilometers.
