Question

Please I need examples on using 111km in calculating the actual distance on ground when the map distance and scale is given

Answer 1

Answer: Do it yourself

Find your scale. Maps have different scales e.g. for an explorers map 1:25,000.

Measure distance on map say in centimetres.

Use a ruler, string, or almost anything, pencil, fingers, a twig or I like a spare piece of paper.

Place against the scale for a direct reading.

Or calculate distance.

Say you measure 4 cm on the map. Then remember in this case 1:25,000.

so 4x1 or 4 = 4x25,000 = 100,000 cm real or actual distance.

In meters divide by 100 = 100,000/100 = 1,000 metres. (= 4cm on map).

or in kilometres divide again by 1,000 = 1,000/1,000 = 1 Kilometre. (= 4cm on map).

Also a tip just proved: 1:25,000 is the same as 4 cm = 1 Km or 1 cm = 1/4 Km real.

And best for walking a 1:50,000 scale map 2 cm = 1 Km or 1 cm = 1/2 Km real.
