A map has a scale of 1 cm = 5 km. On the map, two cities are 3 cm apart. What is the actual distance between these cities? A. 1.7 km B. 5 km C. 15 km D. 17 km
3 cm. x 5 km.
= 15 km.
No.
If you post another answer, please show your work.
To find the actual distance between the cities, we need to use the scale of the map, which states that 1 cm on the map represents 5 km in reality.
Given that two cities on the map are 3 cm apart, we can use this information to set up a proportion:
1 cm on the map / 5 km in reality = 3 cm on the map / x km in reality
To solve for x, we can cross-multiply:
1 cm * x km = 3 cm * 5 km
x km = (3 cm * 5 km) / 1 cm
x km = 15 km
Therefore, the actual distance between the cities is 15 km.
The correct answer choice is C. 15 km.
