BECE Social Studies 2022 Paper

Concept:A representative fraction (R.F.) shows map distance and ground distance in the same unit, written as $1:x$.Formula used:$1 \text{ km} = 1000 \text{ m} = 100,000 \text{ cm}$Solution:Convert $5$ km to centimetres:$5 \text{ km} = 5 \times 100,000 = 500,000 \text{ cm}$So $1$ cm on the map represents $500,000$ cm on the ground.R.F. $= 1:500,000$Answer:Option B ($1:500,000$)
