Study the graph and answer the following question:
(i) Do both bodies start from same position?
(ii) Do they have uniform speed?
(iii) Does anybody have acceleration?
(iv) What is speed of A?
(v) What is speed of B?
(vi) Without actual calculation, can you infer which body is travelling faster?

1. can't be said surely. can start from same point and not too.
2.yes they have uniform spped.
since v=ds/dt=slope of line =const
3. uniform speed means 0 acceleration if it is straight motion.
4.&5. can't be determined without datas.
6.since slope of B is greater than A. so speed of B is greater than A.
that's all.
