Map Reading Measuring the length and distance

Measuring straight line distance between two points. 1. 2. 3. 4. Join the two places with a straight line. Measure the length between them on the map with a ruler. 5. 5 cm Identify the scale of the map: 1 cm to 3. 2 km Do the calculation for the answer: 3. 2 km X 5. 5 = 17. 6 km

Measuring straight line distance between two points. 1. 2. 3. 4. Join the two places with a straight line. Measure the length between them on the map with a ruler. Identify the scale of the map Do the calculation for the answer: Scale X Distance on the map

Finding the actual ground distance of a curved line by using a piece of paper. Use a piece of paper with straight edge. 2. Divide the road into different parts. Each part could be measured as a straight line. 1.

Finding the actual ground distance of a curved line by using a piece of paper. Place the edge of the paper against the first part of the road. 4. Use to tip of a pencil to pin the paper at the end of the first part , the twist the paper till attaches to another straight part. 3.

Finding the actual ground distance of a curved line by using a piece of paper. 5. Same method is applied to measure the remaining straight

Finding the actual ground distance of a curved line by using a piece of paper. 6. Place the paper along a ruler and obtain the map distance of the road in cm.

Finding the actual ground distance of a curved line by using a piece of paper. With reference to the linear scale, measure the actual ground distance of the road from Perth to Sydney. 8. Do the calculation: the scale is 1. 5 cm to 500 km. So the actual ground distance of the road is (10. 7/1. 5 X 500 m)=3567 km 7.
