The position-time (x-t) graphs for two children A and B returning from their school O to their homes P and Q respectively along straight line path (taken as x-axis) are shown in figure. Choose the correct statement (s):

Explanation

(a) A lives closer to the school than B. (because `Op lt OQ`)
(b) A starts from the school earlier than B. When they start, then t=0 at x=0 for A . But for B, t has a finite value when it starts at x=0.
(c ) B walks faster than A. because, the velocity is given by slope of the x-t graph. the slope is more for B than A.
(d) A and B reach home at the same time. because, the value of t corresponding to the points P and Q is same in x-t graph.
(e) B overtake A on the road once because B starts from the school after A and overtakes A.
