A map has a scale of 1:25000. How many kilometres in actual distance is represented by the length 6.8 cm on the map?

Answer 1

To find the actual distance in kilometers represented by 6.8 cm on the map, we need to use the scale ratio of 1:25000.

Since 1 cm on the map represents 25000 cm in reality, we need to convert 6.8 cm to kilometers.

First, we convert 6.8 cm to meters by multiplying it by 0.01 (since there are 100 cm in a meter):
6.8 cm * 0.01 = 0.068 meters

Next, we convert meters to kilometers by dividing by 1000 (since there are 1000 meters in a kilometer):
0.068 meters / 1000 = 0.000068 kilometers

Finally, we multiply this value by the scale ratio of 1:25000 to find the actual distance in kilometers:
0.000068 kilometers * 25000 = 1.7 kilometers

Therefore, the actual distance represented by 6.8 cm on the map is 1.7 kilometers.
