Yashi started walking straight towards the East. After walking 55 m, she turns to the left and walks 15 m straight. She then turns to the right and walks 20 m. Again she turns to the right and walks a distance of 15 m. How far is she from the starting point?

Solution

✅ Correct Option: 3

Start (0,0), facing East. Walk 55m East to (55,0). Turn left (face North), walk 15m to (55,15). Turn right (face East), walk 20m to (75,15). Turn right (face South), walk 15m to (75,0).

Distance from start =752+02=75 m= \sqrt{75^2 + 0^2} = 75\ m.
