1. Ground Speed of Plane

2. Solving Problems Using Vectors A pilot wants to fly on a bearing of 69.2°. By flying due east, he finds that a 50-mph wind, blowing from the south, puts him on course. Find the ground speed of the plane. 69.2 ° Bottom yellow line is the original route of the plane. Red line is the wind. Green line is the new direction of the plane. 50 mph

3. Solving Problems Using Vectors A pilot wants to fly on a bearing of 69.2°. By flying due east, he finds that a 50-mph wind, blowing from the south, puts him on course. Find the ground speed of the plane. 69.2 ° Calculate the angle inside the triangle. 50 mph 90 – 69.2 = 20.8 20.8 °
