Show answer & explanation
Correct answer: B
Concept
A direction-turn problem tracks only the current heading at each turn. A right turn rotates the heading 90 degrees clockwise, while a left turn rotates it 90 degrees anticlockwise.
Application
Asha initially faces south.
Turning right from south makes her face west; walking 2 km does not change that heading.
Turning right from west makes her face north; walking 3 km does not change that heading.
Turning left from north makes her face west.
Cross-check
Using the clockwise cycle north to east to south to west to north, the turns are south to west to north to west. Therefore, Asha is now walking west.
