Point B is 6 km east of point A. Point C is 8 km north of B. Point D is 6 km west of C. What is the position of D with respect to A?
D is 8 km north of A. Moving 6 km east and later 6 km west cancels the horizontal displacement, leaving only the 8 km northward movement from B to C. So D lies exactly north of A at a distance of 8 km.
- A8 km northCorrect
- B14 km north
- C10 km north-west
- D8 km north-east
Explanation
Take A as (0,0). B is (6,0), C is (6,8), and D is (0,8). D lies directly above A, so it is 8 km north of A. The 6 km east and 6 km west movements cancel each other, so 14 km and a north-east position are incorrect.

One question tells you little. A timed set on Direction Tests shows your real accuracy, how long you take and where you lose marks.
