A boy travels a distance of 10m towards south and then he runs towards east and travel 12m in that direction. Calculate yhe total distance travelled by the boy and displacement from his initial position.
Total Distance = sum of distances in each direction (south, then east).
distance between end point and starting point, irrespective of path.
(hint: use Pythagoras theorem, since the two legs are perpendicular to each other).
