Answer:
The real world distance in km between these two cities is 255
Explanation:
we know that
The scale on a map is 1 : 1,500,000
That means-----> 1 cm on a map represent 1,500,000 cm in the real world
or
1 cm on a map represent 15 km in the real world
so
using proportion
Find out the distance in the real world for 17 cm on the map
![(1)/(15)=(17)/(x)\\\\x=15(17)\\ \\ x=255\ km](https://img.qammunity.org/2020/formulas/mathematics/middle-school/c1yiy14mtij659ogk7tsveitsbjncz1od0.png)
