You can put this solution on YOUR website! in what direction must a plane head if it can mantain 350 km/h in still air, wishes to fly 500km in a direction of 040 degrees and the wind is blowing at 56km/h from 100 degrees? how long would the journey take( to the nearest minute)?
===========================
The directions use zero (0) as North, or vertical.
Draw a triangle with 1 side ata 040, 40 degs to the right of vertical.
That's the desired ground track. Put an arrowhead on its end to indicate direction.
Draw another line at an angle of 100 degs and put an arrowhead on it that meets the 1st arrowhead. Label its length at 56.
You can calculate that the angle between the 2 lines where the arrowheads meet is 130 degs.
----
Draw the 3rd line of the triangle and label it 350, the plane's airspeed.
---------------
Now you have a triangle that can be solved.
