Shivani moved a distance of 45 meters towards the north. She then turned to the left and walked for about 15 meters, turned left again and walked 50 meters. Finally, she turned to the right at an angle of 45°. In which direction was she moving finally?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → South-West
Each turn is taken from the direction she is facing at that moment:
She starts facing North and walks 45 m
Facing North, a left turn is West: she walks 15 m
Facing West, a left turn is South: she walks 50 m
Facing South, a full right turn (90°) would be West; a right turn of only 45° stops halfway between South and West, that is, South-West
