a map is drawn to a scale of 1:20000. find the actual distance, in kilometers, between two points which are 15cm apart on the map

1 answer

To find the actual distance in kilometers between two points on the map, we first need to determine the distance on the map.

Since the scale is 1:20000, this means that 1 centimeter on the map represents 20000 centimeters in reality.

Since the two points are 15 cm apart on the map, the distance between them in reality is:

15 cm * 20000 cm = 300000 cm

To convert this distance from centimeters to kilometers, we divide by 100,000 (since there are 100,000 centimeters in a kilometer):

300000 cm รท 100000 = 3 kilometers

Therefore, the actual distance between the two points is 3 kilometers.
