A plane flies in a direction of 24.5 degrees South of West at 290 mph. It encounters a 30.5 mph wind that is heading 21 degrees East of North.
On a coordinate plane, three vectors are in quadrant 3. A ground vector is about 20 degrees from the x-axis, the air vector labeled 290 miles per hour is 24.5 degrees from the x-axis. Wind vector is 30.5 miles per hour from the terminal point of the air vector to the terminal point of the ground vector. It forms a 21 degree angle with a vertical line.
Select the correct ground speed for the plane (rounded to the nearest mph).
