A plane is flying on a course with a vector of <250, 100>, where the 250 is the speed due north, and the 100 is the speed due east. The wind is blowing <25, 5> where the directions are also north and east, in the same order. How fast is the plane flying? All values are in mph.

  1. final course vector
    <275,105>

    magnitude = √(275^2+105^2)
    = 294.36 units of speed
