If actual distance between two places A and B is 110 km and it is represented on a map by 25 mm. Then the scale used is 1: 4400000
From the question it is given that,
Actual distance between two places A and B is = 110 km
Distance is represented on a map by = 25 mm
So, the scale used is = Size drawn on map/ actual distance
= 25 mm/110 km
We know that, 1 km = 1000 m
1m = 100cm
1cm = 10mm
1 km = 10,00,000
So, 110 km = 11,00,00,000 mm
Therefore = 25/11,00,00,000
= 1/4400000
= 1: 4400000
