Dinesh walks 14 m east, then 7 m north, then 6 m west, then 7 m south... He finally stops. How far is he from his starting point and in which direction?
Dinesh is 8 m east of his starting point. His east-west movement nets 14 minus 6, which is 8 m east, and his north and south movements of 7 m each cancel out, leaving no vertical displacement.
- A8 m, eastCorrect
- B20 m, east
- C8 m, west
- D6 m, north
Explanation
Net east-west displacement = 14 - 6 = 8 m east. Net north-south = 7 north - 7 south = 0. So he is 8 m east of the start. The 20 m option adds 14 and 6 instead of subtracting the westward walk.
Did you get it right without looking?
One question tells you little. A timed set on Direction Tests shows your real accuracy, how long you take and where you lose marks.
