The distance between two cities on a map is 7.5 centimeters. The map uses a scale in which 1 centimeter represents 15 kilometers. What is the actual distance between these two cities in kilometers?

1 answer

To find the actual distance between the two cities in kilometers, we need to use the scale provided.

Since 1 centimeter on the map is equivalent to 15 kilometers in reality, we can set up a proportion:

1 cm = 15 km
7.5 cm = x km

Cross-multiplying, we get:

1 * x = 15 * 7.5
x = 112.5

Therefore, the actual distance between the two cities is 112.5 kilometers.
