Answer» le of map is 1:2000000. What is the actual distance between two towns, if they are 4cm apart on the map?One UNIT of length on the plan represents some number of same UNITS of length on the ground,such as 1/1000,etc.This Ratio of map distance to the corresponding ground distance is independent of units of measurement and is called representative FRACTION (R.F.).The representative fraction can be very easily found for a given engineer’s SCALE.If the scale isR.F.= 1/2000000=1/2x 10000x1001cm=20000mThe scale of a map is given as= 1/2000000Two town are 4 cm apart on the map.the actual distance between two towns=4x 20000=80000 m=80000/1000 Km=80KmI hope it's HELP with you!plz mark as branlist..Thank u
