From a certain place Ritu goes 30 km north, then turns right and walks 15 km. After that it turns right and walks 30 km. Tell how far is he from the starting point and what is his direction from there?
Explanation:
Ritu walks 30 km North, 15 km East, and 30 km South. The North and South movements cancel each other out. She is exactly 15 km East of her starting point.
