Priya started walking towards east for 20 m, then took left and walked for 40 m, then turned right and walked for 30 m. Now she turns right and walks 40 m. How far is priya from her starting point ?

1. Priya starts from a point and walks 20 m towards the East.2. She takes a left turn (facing North) and walks 40 m.3. She turns right (facing East) and walks 30 m.4. Finally, she turns right (facing South) and walks 40 m.Her final position is perfectly aligned horizontally with her starting position because her Northward and Southward movements cancel each other out (40 m North, then later 40 m South).Her total distance from the starting point is the sum of her Eastward movements: $20\text{ m}+30\text{ m}=50\text{ m}$.
