Question

A boy starts from his home. After walking 10 km towards north he turns right and walks for 5 km. Again he turns right and walks for 15 km. In which direction is he from his home :

• A. South-East
• B. South-West
• C. North-East
• D. North-West

Answer 1

Answer:

A. South-East

The boy is in the South-East direction from his home.

• Start: He begins at his home, which we can consider as the starting point $(0,0)$.

• First Move: He walks 10 km North.

• Second Move: Turning right faces him East, where he walks 5 km East.

• Third Move: Turning right again faces him South, where he walks 15 km South.

Since he walked 10 km North and then 15 km South, he ends up 5 km South of his original starting latitude. Combined with his 5 km East movement, his final position places him south and east of his home.
