Question 1 View Details
A topographic map of a region is drawn at a scale of 1:25,000. On the map the distance between Town A and Town B measured with a ruler is 6.8 cm and the bearing of the line AB measured with a protractor is 045°. The straight‑line distance between points D and E on the map is 8.0 cm. The river between D and E is shown to meander, and its actual length is 1.3 times the straight‑line distance. The elevation at D is 150 m and at E is 210 m.
Question Parts
(a)
Calculate the actual ground distance between Town A and Town B in kilometres.
(b)
Express the bearing of AB as a quadrant bearing.
(c)
Estimate the actual length of the river segment DE in kilometres.
(d)
Calculate the average gradient of the river segment DE as a percentage.
(e)
State one implication of this gradient for the river’s flow characteristics.

Question 2 View Details
A model of a rectangular agricultural field is drawn on a sheet of paper at a scale of 1 cm : 50 m. On the model the length measured with a ruler is 9.6 cm and the width is 5.4 cm. Within the field a circular pond is shown with a radius of 0.8 cm. In reality the pond is 2.5 m deep.
Question Parts
(a)
Determine the actual length and width of the field in metres and express the area of the field in hectares.
(b)
Calculate the actual area of the pond in square metres.
(c)
Using the pond’s area and the given depth, compute the volume of water in the pond in cubic metres.
(d)
If the field is to be fertilised at a rate of 120 kg of nitrogen per hectare, calculate the total amount of nitrogen fertilizer required for the whole field.

Question 3 View Details
A 1:50,000 scale topographic map shows Town A at latitude 5°30' N and longitude 7°45' E. Using a ruler, the straight‑line distance between Town A and Town B on the map is measured as 12 cm and the bearing from A to B is 135°. The student is required to determine:
Question Parts
(a)
The latitude and longitude of Town B (to the nearest minute).
(b)
The actual ground distance between the two towns in kilometres (to one decimal place).
(c)
The change in latitude (Δφ) and longitude (Δλ) between Town A and Town B expressed in minutes (indicate direction).
(d)
Discuss two possible sources of error in this practical method and suggest how each could be minimised.
