Aditi walks 16 meters towards the west, then turns to her right and walks 16 meters and then turns to her left and walks 12 meters. Again turning to her left, she walks 16 meters. What is the shortest distance between her starting point and her present position?

Solution

✅ Correct Option: 3

Take the start as (0,0)(0,0). Walking 16 m west gives (−16,0)(-16, 0); a right turn faces north and 16 m gives (−16,16)(-16, 16); a left turn faces west and 12 m gives (−28,16)(-28, 16); a left turn faces south and 16 m gives (−28,0)(-28, 0). The north and south legs cancel, so the distance is 2828 m.
