**MathMate**, Monday, September 21, 2009 at 7:31pmDisplacement is a vector. To find the displacement due to multiple legs of a trip, we sum the components (x,y) or (east,north) by resolving each leg into the respective components.

105 km west = (-105,0)

30 km SW = (30cos(225°),30sin(225°))

Sum each component to get the resultant components. The direction can be found with the tan^{-1}(y/x) function.

Post your answer for a check if you wish.
