The scale of a map is 1:3000000. The actual distance between two cities is 120 km. What is the distance between them on the map?

Correct option is A

 
Given:
- Scale of the map = 1 : 3,000,000
- Actual distance between the cities = 120 km
Formula Used:
1. The scale ratio 1 : 3,000,000 means that 1 unit on the map represents 3,000,000 units in real life.
2. Distance on the map = Actual distance / Scale factor
Solution:
1. Convert the actual distance to the same units as the scale. Since the scale is typically in cm, we convert 120 km to cm: 120 km = 120 × 1000 × 100 = 12,000,000 cm
2. Calculate the map distance: Map distance = 12,000,000 / 3,000,000 = 4 cm
Answer: (a) 4 cm
