ANSWER:
112.5 km
EXPLANATION:
Given that the map has a scale of 1cm : 15 km.
This means that 1 cm represents 15 km.
Since 1cm represents 50km, and the towns are 7.5 cm, the distance between both towns in real life will be:
[tex]\frac{15}{1\text{ }}\text{ }\ast\text{ 7.5 = }112.5\text{ km}[/tex]The distance between the two towns in real life will be 112.5 km
