Mr. X starts walking towards the West. After walking 70 m, then he turns to the left and walks 35 m straight. If he now turns left again and walks 30 m, and then he turns to the left and walks a distance of 35 m. How far will he be from the starting point finally?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 40 m
Each turn is taken from the direction he is facing at that moment:
Facing West, a left turn is South (35 m)
Facing South, a left turn is East (30 m)
Facing East, a left turn is North (35 m)
The 35 m South and 35 m North cancel each other, so he ends on the line he started from, \(70-30=40\) m West of the starting point.
