Ok i think the book is trying to noobify me by tricking me... ok here's the problem.
Ok so Earth is the origin
Object A moves in the positive X direction at 0.900c measured from the earth
Object B moves in the positive X direction at 0.800c measured from the earth
Object B is further along on the X axis as object A so B will soon overtake object B.
Observers on the Earth witness A overtake B at a relativistic speed of 0.100c
With what speed is A overtaking B if observed by A?
Shouldnt it be the same, 0.100c?
