Vector A is due West and Vector B is due North. Which of the following represents the subtraction of Vector A - Vector B? O A - B O A - B\fA woman runs 6.2 km South. She then turns around and runs 9.3 km North and then finally turns around once more and runs 4.3 km South. How far and in what direction is she from where she started? O 1.2 km South O 1.5 km North O 3.1 km North O 1.2 km North A small aircraft sets a course with a certain bearing and at a speed of 200mph. A horizontal wind blowing toward the east at a speed of 20 mph causes the aircraft to fly off- course with a speed of 217 mph by an angle of , as shown in the diagram. N 20 mph 200 mph/ 10 217mph W E The angle, #, by which the aircraft is flying off-course is, to the nearest degree, O 30 O 2 O 3A girl bikes 2.8 km South, then 4.6 km East. Finally, she bikes 7.1 km North. How far away is she from where she started and in what direction?
