Concept:Convert every turn into a movement direction and then find the net displacement from the starting point.
Explanation:Start at the original point facing East.
Right turn from East means moving South, so go
20Â m South.
Left turn now means moving East, so go
20Â m East.
Right turn again means moving South, so go
20Â m South.
Right turn again means moving West, so go
40Â m West.
Another right turn means moving North, so go
40Â m North.
Total Southward movement is
20Â m+20Â m=40Â m.
This is fully cancelled by the final
40Â m North movement.
Net East-West movement is
20Â m East and
40Â m West, giving
40 m−20 m=20 m West.
Therefore, the final position is
20Â m West of the original point.
Answer:West (Option B).
