Tom left for his office in his car. He travelled 5 km towards the North and then 10 km towards the East. He then travelled 3 km towards the South. Further, he turned to the West and travelled 2 km. Finally, he turned towards the South and travelled 2 km. In which direction is he from his house and what is the distance?

8 Km East

As we know, QB = OA

QB = QC - BC

= 10 Km - 2 Km            [QC = ED]

= 8 Km                        [QC = 10 Km]

Therefore, OA = 8 Km

(8 Km East direction)
