Question

If the actual distance is 10000 times the distance marked in a map, what is the scale used in the map?

• A. 1 cm : 1 km
• B. 1 cm : 1 m
• C. 1 cm : 100 km
• D. 1 cm : 100 m

Answer 1

The correct option is D 1 cm : 100 m

Let's take the diatance marked in the map as 1 cm.
So the actual distance = 1 cm $\times$ 10000 = 10000 cm
Since we know that 100 cm = 1 m,
We can denote 10000 cm as 10000 $÷$ 100 = 100 m
So the scal used in the map is 1cm : 100 m
