Answer:
The cities are 35 cm apart in map.
Explanation:
The scale on a map is 5 cm : 8 km.
![\texttt{Scale = }(5cm)/(8km)\\\\\texttt{Scale = }(5cm)/(8* 100000cm)=(5)/(800000)](https://img.qammunity.org/2020/formulas/mathematics/high-school/6jr114xtwuzx43zpff1h1xyvewjgjqqxyu.png)
Now we need to find how much is the distance in map if the original distance is 56 km.
Distance in map = Scale x Original distance
![\texttt{Distance in map = }(5)/(800000)* 56km=(5* 5600000cm)/(800000)=35cm](https://img.qammunity.org/2020/formulas/mathematics/high-school/o6t5mdip91a6rqy3n4fsewwu5iczyhfm86.png)
The cities are 35 cm apart in map.
