A plane is flying due south at a speed of 192 mph. a wind is blowing in at 53 degrees at 13 mph. what is the bearing of the plane?

Answer 1

Not sure what notation you are using when you say
"blowing in at 53° "

is North your 0° and you are going clockwise, or
is 0° your positive x - axis and you are going counterclockwise ?

Answer 2

Assuming the normal 0° at North, and ignoring the misuse of the word "bearing", I'd say that the resultant heading of the plane is 246.7°

Answer 3

I meant 336.7°
