If the scale of a map is 2cm to 1km, what is the ground distance if the distance between two towns on the map is 20cm
Answer Details
If the scale of a map is 2cm to 1km, it means that for every 2 centimeters on the map, there is a real-world distance of 1 kilometer. To find the ground distance between two towns on the map, we need to convert the distance on the map into a real-world distance.
If the distance between the two towns on the map is 20cm, we can start by calculating how many kilometers it represents in the real world. Since the scale is 2cm to 1km, we can divide the distance on the map by 2 to get the real-world distance:
20 cm / 2 = 10 km
Therefore, the ground distance between the two towns is 10 kilometers.
So the answer is: 10km.
