Question

If 3.2 cm on the map corresponds to an actual distance of 4 km, what is the scale of the map?

A. 1:1250
B. 1:1000
C. 1:800
D. 1:625

Answer 1

The scale of the map can be found using a proportion. The scale of the map is 0.8 cm : 1 km, which can be simplified to 1:1250. The correct answer is A. 1:1250.

Step-by-step explanation:

To find the scale of the map, we need to set up a proportion using the given information. We have 3.2 cm on the map corresponding to 4 km in actual distance. So the proportion is:

3.2 cm / 4 km = x cm / 1 km

Next, cross multiply and solve for x to find the scale measurement in centimeters for 1 km:

x = (3.2 cm * 1 km) / 4 km = 0.8 cm

Therefore, the scale of the map is 0.8 cm : 1 km, which can be further simplified to 1:1250. Hence, the correct answer is A. 1:1250.
