Manik walks 4 m towards east. Then he turns right and stops after walking 4 m. What is the shortest distance between the starting point and the ending point?
Explanation:
Manik forms a right-angled triangle with sides 4 m East and 4 m South. The shortest distance (hypotenuse) = √(4² + 4²) = √(16 + 16) = √32 = 4√2 m.
I walked 5 meters in East and then took a left turn and again walked 5 metres. From there I walked 3 meters towards North. Then I took two consecutive left turns, and walked 3 meters each time. In which direction am I now from the starting point?
Explanation:
Path: 5m East, 5m North (left turn), 3m North = 8m North total. First left turn from North puts me West 3m. Second left turn puts me South 3m. Total East = 5 - 3 = 2m. Total North = 8 - 3 = 5m. Since I am East and North of the start, the direction is North-East.
