An airplane moves at 300 mi/hr relative to the air. It must fly from city A to city B, 600 miles due east. One day the wind is blowing at 100 mi/hr in a direction of 30 degrees north of east. Draw a diagram.

b. What will the velocity of the plane relative to the ground (value and direction)?

c.After the 2 hours flight, how far is city B from the plane, and in what direction?
