Bar scales show scale using a graphic format. Each one of those centimetres represents 50m, so we get the actual distance between A and B to be . To find the real-life distance between these points, we need to measure them on the map. Scales help us work out distance to our destination and therefore how long it will take us to get there. There are three main ways that scale is indicated on a map: graphic (or bar), verbal, and representative fraction (RF). ADVERTISEMENTS: (iii) Details of cities, towns, villages are shown.
