To find the actual distance between the two towns based on the map scale, you can use the given scale of 1 cm = 80 km.
If the two towns are 5 cm apart on the map, you can calculate the actual distance as follows:
\[ \text{Actual distance} = \text{Distance on map} \times \text{Scale factor} \] \[ \text{Actual distance} = 5 , \text{cm} \times 80 , \text{km/cm} \] \[ \text{Actual distance} = 400 , \text{km} \]
Therefore, the distance between the two towns is 400 km.
