Question

On a map with a scale of 1 cm = 3000000 cm, the distance
between A and B is 18 cm.
a) What is the actual distance (in km) between A and B?
b) Two towns are 15 km apart. What would the distance between
these towns on a map be?

Answer 1

Answer:

1cm on a map represents 4000000

5cm on a map represents =5×4000000=20,000,000‬cm

1km=1000m

1m=100cm

∴1km=1000×100=100000cm

∴100000cm=1km

∴20,000,000‬cm=

100000

20,000,000‬

km=200km

Thus, the actual distance between two towns is 200km.
