Question : 1

Total: 50

Solution:

Concept:

Representative fraction compares map distance to ground distance using the same unit of measurement.

Explanation:

The map scale shows that

1\text{ cm}

on the map equals

0.5\text{ km}

on the ground.

Convert kilometres to centimetres:

0.5\text{ km} = 0.5 \times 100{,}000 = 50{,}000\text{ cm}

So the ratio of map distance to ground distance is

1 : 50{,}000

This is the representative fraction of the scale.

Answer:

1 : 50{,}000
