A map has a scale of 5 cm : 12 km. Two cities are 7 cm apart on the map. To the nearest tenth of a kilometer, what is the actual distance corresponding to the map distance?

Respuesta :

You can set up a proportion to solve the problem. So do cm/km=cm/km
Map scale= 5/12
City: 7 cm/x
Proportion= 5/12= 7/x 

Use cross products to solve the proportion... And you get 16.8 km
