1. How do we use scale on a map
1.1. Map scale

1.1.2. Graphic scale: (bar scale) shows the equivalent distance on a bar divided into equal segments, usually 1 cm.
1.2. How to use scale to calculate distances
1.2.1. a) Interpret the map scale 1/8,250,000. So 1cm is equivalent to 82,5 Km ( or 8.250, 000 cm )
1.2.1.1. b) Measure the distance you wish to calculate
1.2.1.1.1. c) Do the calculations 1/8,250,000= 6cm/x x=8,250,000*6/1 x=49.500.000 cm
