2d because one moves south 1d and the other moves north 1d
d because displacement is 'the difference between the path of the initial and final position covered by a moving object'
in this question the distance and displacement is the same, as the opposite direction can be said equal to as north-south direction. The two cars covers distance of d in an hour. Therefore the displacement will be d for each for the car assuming the initial position is same.
in this question the distance covered in one hour is d ,but since they are in the opposite direction, the displacement of one car is the negative of the other .they cancel each other out and the total displacement is 0.
i am confused as i got three different answers from u all. Bt still thanx
