Solve the all parts of following problem:
Problem: A car drives north at 32mi/h for 10 min and then turns east and goes 5.0 mi at 56mi/h. Finally, it goes southwest at 40mi/h for 6.0 min.
Part A: Determine its average velocity for this trip.
Part B: Determine the car's displacement.
I need help to solve the above question and express your answers using two significant figures separated by a comma. Assume that the positive x and y axes are directed to the east and north, respectively.
