Explanation

The Pole Star, also known as Polaris, is situated in the direction of the Earth's axis and remains nearly stationary in the sky, serving as a reliable indicator of geographic North in the Northern Hemisphere [3]. To determine cardinal directions relative to North, one can use the standard orientation where, if a person faces North (towards the Pole Star), East is to their right, West is to their left, and South is behind them. In this scenario, the person needs to travel 5 km East to reach his village. Since East is 90 degrees clockwise from North, the person must walk in a direction such that the Pole Star (North) is positioned to his left side. This orientation ensures he is moving directly Eastward toward his destination [3].
