( x and y coordinates are in miles)

Point A departure (0,0)

Point B (?, 300)

Point C destination (0,500)

An airplane will head due north at 300mi/h to a destination 500 miles away. From point A to point B, the plane will experience a 40 mi/h crosswind flowing in the direction N 30° E. Then from point B to point C, the plane will experience a 40 mi/h crosswind flowing in the direction N 30° W .How long will it take the plane to to go from point A to point C and what direction must it head in ? (find the true speed and direction of the airplane)

( in an attempt to clarify the question, basically) The airplane flies to point B under the influence of a wind in the direction N30E. The wind then changes to N30W, and the airplane flies under its new influence in flying from point B to point C (0, 500).

any advice is greatly appreciated
