TS EAMCET 11-Sep-2020 Shift 1 Solved Paper

Let us use the conventional directions, as shown in figure, to solve this problem.According to question, let us draw the diagram. There are two possible diagrams.
Clearly, ‌‌CE=AB=30m⇒CD=30√2m
Using Pythagoras theorem,
(CE)2+(DE)2=(CD)2
⇒‌‌DE=30m
Now, it is clear that Case I is not possible.
Using Case II,
Clearly, displacement of the person is
End point - Start point =DA  (along West)
and ‌‌DA=DE−AE
=30m−20m=10m (along West)
