The representative fraction of a map is 1:25,000. How many centimetres on the map represent 5 km on the ground?
Answer and explanation
Correct answer: A. 20 cm
- Step 1: 5 km = 500,000 cm. Step 2. Map distance = 500,000 / 25,000 = 20 cm. Answer: 20 cm. Why not the others: 5 cm: That ignores the scale. 200 cm: That is out by a factor of ten. 125 cm: That multiplies 5 by 25.
