Ответ:
The actual distance between the cities is 1,200 Km
Step-by-step explanation:
Scaling
Objects can be represented in a reduced or augmented size by using scaling which is multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.
We are given the scale on a map as 1:20,000,000.
Two cities are 6 cm on the map. The actual distance is obtained by multiplying:
6 * 20,000,000 = 120,000,000 cm
Divide by 100 to convert to meters and by 1,000 to convert to km 120,000,000/100/1,000=1,200 Km
The actual distance between the cities is 1,200 Km
