    A remote controlled boat is placed in a river. The boat produces a driving speed of 1.54ms^-1 at an angle of 60.0 degrees to the current (travelling with the current). The river is flowing at 0.20ms^-1. By resolving the vectors into their horizontal and vertical components, show that the resultant velocity of the boat is 1.6ms^-1 at an angle of 54 degrees to the current.

    To get the resultant you need to add the velocities together... which you do by drawing the vectors connected tip to tail.

    it doesn't matter which order you choose so you can just pick the simplest to draw which imo would be drawing the current first followed by the boat velocity. the resultant velocity is the vector joining the tail end of the first vector to the tip end of the last vector.
