A map has a representative fraction of 1:50,000. A distance of 2 cm on the map represents what ground distance?
Correct answer: C. 1 km
- A. 100 m
- B. 500 m
- C. 1 km
- D. 10 km
Explanation
At a scale of 1:50,000, 1 cm represents 50,000 cm, or 500 m. Therefore, 2 cm represents 1,000 m, which is 1 km.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
