Ms. X moves 20 metres in the East direction and then turns to her left and walks 15 metres and then turns to her right and moves 25 metres. After this, she turns to her right and moves 15 metres. Now, how far is she from the starting point?
A
35 metres
B
40 metres
C
45 metres
D
None of these
Correct Option:
C
Explanation
She first moves 20 m east, then 15 m north. After turning right she moves another 25 m east, and the next right turn takes her 15 m south. The 15 m north and south movements cancel, leaving a net eastward displacement of 20 + 25 = 45 m.
