As the angle has been measured from north, the north component should be calculated with cosine and the west component should be calculated with sine: Vn = 835km/h*cos(41.5) =625 km/h Vw = 835km/h*sin(41.5) =553 km/h In order to calculate the distance travelled after 2.5 hours, we should use the uniform linear movement formula: d=v*t total distance (modulus of the distance)= 835km/h*2.5h=2088 km Or we can calculate each component (north and west): dn=625 km/h*2.5h=1563 km dw=553 km/h*2.5h=1383 km
