A plane flies 429 km east from city A to city B in 45.0 min and then 969 km south from city B to city C in 1.40 h. For the total trip, what are the

(a) magnitude (in km) and

(b) direction of the plane's displacement, the

(d) direction of its average velocity, and

(e) its average speed (in km/h)? Give your angles as positive or negative values of magnitude less than 180 degrees, measured from the +x direction (east).
