Answer:

60.15 km

Step-by-step explanation:

If 6 km on the map represents 4 mi on land, then we'd get the answer by using the relation

6 km -> 4 mi

x km -> 40.1 mi

Where x km is the length on the map we're looking for. If we cross multiply

6 * 40.1 = 4x

240.6 = 4x

x = 240.6/4

x = 60.15 km.

That is the length we're looking for

If the scale of a map is 2 centimeters=21 kilometers, then what is the actual distance of 14 millimeters?

Ad libitum [116K]

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 $\times$ 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:

$\frac{d}{14}=\frac{21}{20}$

Multiplying both sides by 14, we get:

$\frac{d}{14}\times 14=\frac{21}{20}\times 14\\d=\frac{21\times 14}{20}=\frac{147}{10}=14.7\ km$

Therefore, the actual distance of 14 mm is 14.7 km.
