Sanjay went 70 metres in the East before
turning to his right. He went 10 metres before
turning to his right again and went 10 metres
from this point. From here he went 90 metres
to the North. How far was he from the starting
point?

Answer:
Lets solve it by taking vectors
so 70i-10j-10i+90j
so it is 60i+80j
Now, since the question is asking about displacement,so it is √(60^2 +80^2)
So the answer is 100 m
