An airplane flies horizontally from east to west at 314 mi/hr relative to the air. If it flies in a steady 32 mi /hr wind that blows horizontally toward the southwest (45 south of west), find the speed and direction of the airplane relative to the ground. Assume that the vector w gives the direction and speed of the wind, the vector v, gives the direction and speed of the airplane relative the air, and the vector v gives the direction and speed of the airplane relative to the ground. Place the vectors in a coordinate system. Choose the correct diagram below. OB. Oc. OD The speed of the airplane is approximately (Simplify your answer. Do not round until the final answer.
