Concept:Representative Fraction (RF) compares map distance with ground distance in the same unit.
Explanation:From the linear scale provided in the map extract, measure the distance between 0 and 2 on the scale bar.
Using a ruler, this distance is
1 cm on the map.
According to the scale bar, this
1 cm represents
1 km on the actual ground.
Now convert both distances into the same unit, i.e. centimetres.
We know that
1 km =
1000 m =
100,000 cm.
Therefore, the scale is:
1 cm :
100,000 cm.
This can be written as a representative fraction:
1:100,000.
Answer:The scale of the map in Representative Fraction (RF) is
1:100,000.
Correct option:
B. 1:100,000.
