Question

If the actual distance of 80 km between City A and City B is represented in a map by a distance of 4 cm, what will be the actual distance of City C from City A, if it is represented by a distance 7 cm in the map?

• A. 100 km
• B. 120 km
• C. 140 km
• D. 160 km

Answer 1

The correct option is C 140 km

Actual distance between A and B = 80 km
Distance between A and B in the map = 4 cm
So if 4 cm is 80 km actually,
and 80 $÷$ 4 = 20,
1 cm in the map will be 20 km actaully.
Distance between A and C in the map = 7 cm

So actual distance between A and C = 7 $\times$ 20 = 140 km.
