Find the scale of the map if 4.5 cm on the map corresponds to 18 km. Find the scale of the map if 6 dm

Find the scale of the map if 4.5 cm on the map corresponds to 18 km. Find the scale of the map if 6 dm on the map corresponds to 2460 km.

First task.
We convert the distance from kilometers to centimeters.
1 km = 100000 cm.
18 km = 18 * 100000 = 1800000 cm.
Determine the scale.
We divide the distance on the ground by the distance on the map.
1,800,000 / 4.5 = 400,000.
The scale is 1: 400000.

Second task.
We translate the indicated distance values into centimeters.
6 dm = 6 * 10 = 60 cm.
2460 km = 2460 * 100000 = 246000000 cm.
Determine the scale of the map.
246,000,000 / 60 = 4,100,000.
The scale will be 1: 4100000.
Answer: The scale of the maps is 1: 400000 and 1: 4100000.
