From her house, Sana walks 50 m towards the East, then 50 m towards the North and then 20 m towards the West. In which direction is she now from her house?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → North-East
Keep a running total of the distance east (or west) and north (or south) of the house; the two leftover parts give the direction.
50 m East: 50 m east of the house
50 m North: 50 m east, 50 m north
20 m West: \(50-20=30\) m east, 50 m north
She is both north and east of the house
Sana is to the North-East of her house.
