Question
How is a distance on a map measured by a piece of twine?
Solution
Take the piece of the twine, make a knot at one end and place
the knotted end on the starting point of the distance to .be measured. Now move the twine along the object to be measured by slowly placing the twine bit by bit along the route following each bend or curve as closely as possible. When you reach the end of the route you are measuring, mark that end with ink. Now place the twine on the scale with the knotted end at 0 and see how far the ink-marked end reaches on the scale. Measure the length and convert into kilometres. If the distance to be measured is longer than the printed scale on the map, place the twine on the ruler in the same way, calculate the number of centimetres it covers and convert that into kilometres.
