whats the magnitude and direction of a plane traveling 120 killimeter per 1 hour for an hour and 30 min then turns and goes 45 degrees west and north at 150 kilomiters per hour for 3hours
-------
1st leg DATA:
x-coordinate:: time*rate*cos(bearing) = 1.5*120*cos(?)
y-coordinate:: tim*rate*sin(bearing) = 1.5*120*sin(?)
---
Comment:: You did not post the bearing for the 1st leg,
--------------
2nd leg DATA:
x-coordinate:: 3*150*cos(135) = -318.19
y-coordinate:: 3*150*sin(135) = 318.19
-----
Add the x-coordinates to get the coordinate of the finish point
Add the y-coordinates to get the coordinate of the finiah point.
------
Assume those final coordinates are (a,b)
Then final bearing is tan^(-1)(b/a)
And final distance = sqrt[a^2+b^2]
