Question

If the distance between two towns is 5 cm on the map and 50 km in real life, then find the scale of the map. [2 Marks]

Answer 1

Solution:

The scale of the map is the ratio of the distance on the map to the corresponding distance in real life. (0.5 Mark)

The distance between two towns on the map and in real life are 5 cm and 50 km respectively.

Hence, 5 cm on the map corresponds to 50 km in real life.

Scale of the map
= 5 cm : 50 km
= 1 cm : $\frac{50}{5}$km (1 Mark)
Therefore, the scale of the map is 1 cm : 10 km (0.5 Mark)
