Question

Jatin leaves his house and walks $12$ km towards North. He turns right and walks another $12$ km. He turns right again, walks $12$ km more and turns left to walk $5$ km. How far is he from his home and in which direction?

• A. $7$ km East
• B. $10$ km East
• C. $17$ km East
• D. $24$ km East

Answer 1

The correct option is C $17$ km East

Let us consider a Cartesian plane thinking positive $X$-axis as East;negative one as West;positive $Y$-axis as North;negative as South, Jatin walks along positive $Y$ axis $12Km$;after that parallel to $X$ axis he walks $12Km$.After that immediately he walks parallel to $Y$ axis towards negative direction $12Km$.Finally he moves $5Km$ towards positive $X$ direction on $X$ axis.Hence he will be at a distance of $17Km$ from the origin that is from starting place.
