======
1-hour coordinates::
x coordinate:: 340*cos(78 deg)+ 40cos(326 deg) = 103.85
y coordinate:: 340*sin(78 deg) + 40sin(326 deg) = 310.20
-------
distance in 1-hour
d = sqrt[103.85^2+310.20^2] = 327.12 km/hr

Aircraft use knots for speed, and they don't use "12 degs East of North" or "34 degs South of East."
