The position-time (x-t) graphs for two children A and B returning from their school O to their homes P and Q respectively are shown in Fig. Choose the correct

entries in the brackets below ;

(a) (A/B) lives closer to the school than (B/A)

(b) (A/B) starts from the school earlier than (B/A)

(c) (A/B) walks faster than (B/A)

(d) A and B reach home at the (same/different) time

(e) (A/B) overtakes (B/A) on the road (once/twice).

##### Solution :-

(a) A lives closer to the school than B, because A has to cover shorter distances [OP < OQ],

(b) A starts from school earlier than B, because for x= 0, t = 0 for A but for B, t has some finite time.

(c) The slope of B is greater than that of A, therefore B walks faster than A.

(d) Both A and B will reach their home at the same time.

(e) At the point of intersection, B overtakes A on the roads once.
