Question
The distance between the two cities A and B is 5 km. It is represented by a line of 5 cm on the map. Calculate the distance and give the answer in RF.
Solution
Representative Fraction (R.F.) = `"Distance on the map"/"Distance on the ground"`
Given, Distance on the map = 5 cm
The distance on the ground = 5 km
∴ R.F. = `(5 "cm")/(5 "km")`
Converting km to cm; 5 km = 500000 cm
So R.F. is 5 : 500000
i.e. R.F. is 1 : 100000
