let here North direction is along +Y and South direction is along -Y
similarly East direction is towards +X and west direction is towards -X
now it is given that
first it moves 235 km north
then it moves back 126 km south
then again he moves north
now the total displacement is given as
so final displacement of train is 154 km North
