Solution (By JKExamLibrary)
West 20 m. Left (South) 40 m. Left (East) 20 m. She is back on the initial vertical line but 40 m South. Then right (South) 20 m. Total distance is 40 + 20 = 60 m South.
In the morning, Shivani walks 3 m in the direction of sunrise. She takes two consecutive left turns and walks 8 m and 3 m respectively after each turn. In which direction is she now moving with respect to the starting point?
Explanation:
Sunrise is in the East. She walks 3m East. First left turn (North) for 8m. Second left turn (West) for 3m. Her East and West movements cancel out. She is exactly 8m North of her starting point.
