To determine the distance between the two cell towers on a map with a scale of 1 centimeter = 1 kilometer, you simply need to convert the actual distance into the map distance using the provided scale.
Since the actual distance between the two towers is 4 kilometers, you can use the scale to find the corresponding distance on the map:
1 centimeter = 1 kilometer
Therefore, for 4 kilometers:
Distance on map = Actual distance in kilometers × Scale factor Distance on map = 4 kilometers × (1 centimeter / 1 kilometer)
The kilometers cancel out, leaving you with:
Distance on map = 4 centimeters
So, the two cell towers are 4 centimeters apart on the map.
