Example (2)
the distance between two cities is 60km . Find the map distance
between them on the map with drawing scale 1 : 200 000
D: R
1 : 200 000
….. : 60 km
1 × 60 × 100000 = 30cm
Length in drawing =
200000
Example (3)
the map length between two cities is 7.5 cm . Find the real distance
between if the map is drawn in a scale 1 : 200 000
D: R
1 : 200 000
7.5 : …….
The real Length = 7.5 × 200000 = 15 km
