1. Rachel starts walking towards North. After walking 15 metres, she turns towards South and walks 20 metres. She then turns towards East and walks 10 metres. Then, again, she walks 5 metres towards North. How far is she from her starting point and in which direction ?

Let the starting point be A and final point be D. Her route can be traced as follows
hence we can see that she is 10m East of her initial position.
