The distance between two cities on a map is 3.5 centimeters. the map uses a scale in which 1 centimeter represents 20 kilometers. what is the actual distance between these two cities in kilometers?

If the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers. The actual distance between these two cities in kilometers will be 70 kilometers

Using this formula

Actual distance=Distance×Kilometers

Where:

Distance=3.5 centimeters

Kilometers=20 kilometers

Let plug in the formula

Actual distance=3.5 centimeters×20 kilometers

Actual distance=70 kilometers

Inconclusion If the distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers. The actual distance between these two cities in kilometers will be 70 kilometers
