If 5cm represents 20km, which means
5cm = 2000000
then, 1cm represents = 2000000/5
Which is = 400000
Therefore, RF = 1 : 400000
Explanation:
- A "Representative fraction" is a ratio/fraction which "expresses" the "mathematical relationship" between "Land's actual length & length on the Map" such as 1:25000 & is "indicated" by a "fraction" whose "numerator" is "1" always. This "fraction" is generally "abbreviated" as "RF". Therefore,
- "Representative Fraction" (RF) = "Map distance/Ground distance"
- The measurement unit of "distances"in the "denominator & numerator" is the "same". for example, if we say RF of a map is 1/200000 or 1:200000, it implies that 1 unit on the"map" "represents 200000 units on the "ground". If the measurement unit say is CM, we would say 1cm on the "map" "represents" 200000 cms on the "ground". Similarly if the measurement unit is an"inch", we would say 1inch on the "map" is 200000inches on the "ground"
