To calculate the actual distance between the towns, you can use the scale provided on the map.
Scale: 1 : 500,000
The distance on the map from the two towns is 7 cm.
Actual distance = (Distance on map) * (Scale)
This means the actual distance is 7cm * 500000
Actual distance = 3,500,000 cm
To convert centimeters to kilometers, divide by 100,000 (since there are 100 centimeters in a meter and 1,000 meters in a kilometer):
Actual distance in kilometers = 3,500,000 cm / 100,000 = 35 km
Therefore, the actual distance between the towns is 35 kilometers.
