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

Answer

(i) A, B (ii) A, B (iii) B, A (iv) same (v) B, A, once

Explanation

By observing the graph, position of A (Q) is greater than position of B (P) i.e. B lives farther than a and also the slope of x-t curve for A & B gives their velocities `v_(B) gt v_(A)`
