Question 42
AÂ student cycles 2 km North, then turns West and cycles 2.5 km, then turns South and cycles 2 km, then turns to his left and cycles 4.5 km. Where is he now with respect to the starting position?
Solution
Let the student starts from point A and cycles 2 km North to reach B, then turns West and cycles 2.5 km to point C, then turns South and cycles 2 km, then turns to his left and cycles 4.5 km towards east to stop at point E.
=> AE = $$4.5-2.5=2$$ km
$$\therefore$$ He is 2 km east with respect to the starting position.
