In a tourist map, 4 cm represents 160 km. What is the real distance (in km) between two towns that are 9 cm apart on the map?

Step-by-step solution

1. Find the scale: $4\text{ cm}:160\text{ km}\Rightarrow 1\text{ cm}:40\text{ km}$
2. Multiply the map distance by the scale: $9\text{ cm}\times 40\text{ km/cm}$
3. Compute: $9\times 40=360\text{ km}$
