A map is drawn to a Representative Fraction (RF) scale of $1 : 200,000$ . What is this scale expressed as a statement scale?

The statement scale is

1\text{ cm represents } 2\text{ km}

An RF of

1 : 200,000

means

1\text{ cm}

on the map equals

200,000\text{ cm}

on the ground. Dividing

200,000\text{ cm}

100,000

converts the ground distance to

2\text{ km}

, yielding the statement scale of

1\text{ cm represents } 2\text{ km}

Understand the Representative Fraction (RF)

1\text{ cm}

on the map represents

200,000\text{ cm}

on the actual ground.

An RF scale of

1 : 200,000

indicates a 1-to-200,000 ratio in identical measurement units.

Convert ground centimeters to meters

\frac{200,000\text{ cm}}{100} = 2,000\text{ m}

There are

100\text{ cm}

1\text{ m}

Convert ground meters to kilometers

\frac{2,000\text{ m}}{1,000} = 2\text{ km}

There are

1,000\text{ m}

1\text{ km}
