A boy runs 4 km towards the East, then turns right and runs 6 km, then turns left and runs 8 km, again turns left and runs 3 km, again turns left and runs 4 km, and then turns right and runs 1 km. In which direction is the boy facing now?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → North
Turning right moves the facing a quarter turn clockwise (East → South → West → North), and turning left a quarter turn anticlockwise. The distances do not change the facing; only the turns do.
He starts by running East.
Right turn: East → South (6 km)
Left turn: South → East (8 km)
Left turn: East → North (3 km)
Left turn: North → West (4 km)
Right turn: West → North (1 km), and he is still facing North
