Question

Calculate the real-life distance in meter(m) shown by 2cm on map. Using the scale 1:20 000 000 and 1:10 000

Answer 1

1:20 000 000 and 1:10 000 means that 1 cm contains 20 000 000 cm (200 km) and 10 000 cm (0.1 km) correspondingly. Thus, 2 cm is 400 km on the first map and 0.2 km (or 400 m) on the second.
