Question

a map was drawn to the scale of 1:400. if the distance between two places on the map is 5cm what is the actual distance (in km) between these two places

Answer 1

Step-by-step explanation:

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.

Answer 2

Step-by-step explanation:

1 cm on a map represent-4000000

5 cm on a map represent- 5× 4000000= 20,000,000cm

1km - 1000m

1m - 100cm

: 1km -1000×100-100000 km

: 100000cm -1km

20,000,000 cm -100000

20,000,000

200 km

Thus , the actual distance between two towns is 200km
