Question

The scale of a map is 1:20,000. On the map the distance between 2 towns is 9cm. Work out the real distance between the towns. Give your answer in kilometers.

Answer 1

well, that would be

9*20000 cm

Just change that to km

or, to make things easier, 20000cm = 200m = 0.2km

so,

9cm = 9*0.2 km

Answer 2

1.8km
