draw a diagram. This is nice and easy, since you have a right triangle. The distance traveled by the plane in t hours must form the hypotenuse of the triangle, so
(40t)^2 = (20t)^2 + 500^2
t = 25/√3 = 14.434 hours.
Now you can figure the distance and the angle θ (west of north) such that tanθ = 20t/500
(40t)^2 = (20t)^2 + 500^2
t = 25/√3 = 14.434 hours.
Now you can figure the distance and the angle θ (west of north) such that tanθ = 20t/500
