Concept:

Representative fraction compares map distance with ground distance in the same unit.

Explanation:

Convert the ground distance to centimetres:

5\text{ km} = 5 \times 100{,}000 = 500{,}000\text{ cm}

.

So the scale is

1\text{ cm} : 500{,}000\text{ cm}

.

Thus, the representative fraction is

1:500{,}000

.

Answer:

1:500{,}000
