21 cm : 588 km

Answer 2

The cities are 588 km apart from each other.

Step-by-step explanation:

Since we have given that

9 cm represents 252 km

So, using "Unitary method", we get that

$1\ cm=\dfrac{252}{9}=28\ km$

Distance between the two cities on a map = 21 cm

So, the number of kilometers would be

$21\ cm=28\times 21=588\ km$

Hence, the cities are 588 km apart from each other.
