Intermediate November 2022 Unit 2 Q9
9. Point A and point B are shown in the scale drawing below.
(a) Point C is 35 km from point B on a bearing of 300°.
Complete the scale drawing to show the position of point C. [2]
Complete the scale drawing to show the position of point C. [2]
On screen this diagram may not be shown at actual size. To measure it, use the question paper (PDF) printed at 100%.
(b) Use your scale drawing to calculate
- the actual length of AC, in kilometres,
- the bearing of point C from point A. [2]
Actual length of AC = …………… km
Bearing of point C from point A = …………… °
| Scheme | Marks | Comments |
|---|---|---|
| Position of C 300° from B | B1 | Allow tolerance of ±2°. Allow any unambiguous indication that the correct bearing has been drawn (e.g. dot, cross). |
| Position of C 7cm from B | B1 | Allow tolerance of ±2 mm. |
| Scheme | Marks | Comments |
|---|---|---|
| (AC =) 53 (km) | B1 | Strict FT ‘their AC’ × 5, with tolerance of ±1 km. |
| Bearing = 018° | B1 | Strict FT from their diagram. Must be a three-figure bearing. Allow tolerance of ±2° |
