Solution
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.
Explanation:
∵ Scale of map = `"Size drawn"/"Actual size"`
= `(25 mm)/(110 km)`
= `(25 mm)/(110000000)` ...[∵ 1 km = 110000000 mm]
= `1/4400000`
Hence, the scale used is 1 : 4400000.
