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
