Answer 2

Answer:

As usual, our starting point will be the point where the N-S and E-W lines intersect, as has been illustrated alongside. We follow her movement as has been asked of us in the question and finally arrive at a point in the east direction. Now the problem before us is to find her distance from the starting point. We will have to calculate it indirectly because there is no direct way to do so. If you look carefully, the two distances i.e. 50 and 60 metres, if joined together give us the distance traveled by her on the eastern side, taken from the starting point. If you transpose this line connecting 50 and 60 metres, you will see that this is exactly the distance traveled by her on the eastern side. So the answer in this case is 110 metres east.
