How to figure out motion in two dimensions?

A sailboat runs before the wind w/a constant speed of 3.2 m/s in a direction of 42 degrees north of west How far (a) west and (b) north has the sailboat traveled in 25 min? (Please show steps)How to figure out motion in two dimensions?
V= 3.2 m/s





V.north = V sin42


V.west = Vcos42


d.west = V.west *t


d.north = V.north *t
