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?
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.
To calculate the actual distance represented by 6.8 cm on the map, you need to use the scale ratio of 1:25000.
Since the scale is given as 1:25000, it means that 1 cm on the map represents 25000 cm in actual distance.
First, convert the length on the map (6.8 cm) into the corresponding length in actual distance:
6.8 cm * 25000 cm = 170,000 cm
Next, convert the length in centimeters to kilometers:
170,000 cm รท 100,000 = 1.7 km
Therefore, 6.8 cm on the map represents an actual distance of 1.7 kilometers.
