Answer:
14.7 km
Step-by-step explanation:
Given:
Scale of a map is 2 cm = 21 km.
We know that, 1 cm = 10 mm
Therefore, 2 cm = 2 10 = 20 mm
Therefore, the scale of the map is, 20 mm = 21 km
Now, let the actual distance be 'd' km for 14 mm.
Using proportion of the two quantities, we get:
Multiplying both sides by 14, we get:
Therefore, the actual distance of 14 mm is 14.7 km.
