A plane flys 230 km due north. The wind is blowing west at 85 km. what direction is the plane flying. Calculate the actual speed of the plane. What is the hearing from North?

Answer 1

X = Vw = -85 km/h.
Y = Vp = 230 km/h.

a. Vr = sqrt(X^2 + Y^2) =

b. Tan A = Y/X = 230/-85 = -2.70588.
A =-69.7o=69.7o N. of W. = 20.3o W. of
N. = Bearing.
