1.	The distance between 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.
Answer» Representative Fraction (R.F.) = Distance on the map / Distance on the ground Given, Distance on the map = 5 cm 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

The distance between 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.

Answer»

Representative Fraction (R.F.) = Distance on the map / Distance on the ground Given, Distance on the map = 5 cm

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
