An airplane's velocity with respect to the air is 580 miles per hour, and its bearing is 332 degrees. The wind, at the altitude of the plane, is from the SW and has a velocity of 60 mph. What is the true direction of the plane, and what is the speed with respect to the ground?

• calculus -

580 at 332° = (-272,512)
60 from SW = 60 at 225° = (-42,-42)

add them up to get (-314,470) = 565 at 326°
