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 . Choose the
.
a.` (A//B)` Iives closer to 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//differnt) time.
e. (A//B) overtakes 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)`
