If i travelled 3 km north and 4 km west what is the total distance covered and magnitude of displacement in km?

Suppose you first walk 9.5 m in a direction 20.0° west of north and then 17.5 m in a direction 40.0° south of west. Part A: How far are you from your starting point in meters?  Part B: What is the angle, in degrees, of the compass direction of a line connecting your starting point to your final position measured south of west?  Part C: Repeat part A, but for the magnitude of the displacement in meters for the second leg where you walk 17.5 m in a direction 40.0° north of east.  Part D: Repeat part A, but now you first walk 9.5m in a direction 40.0° south of west and then 17.5 m in a direction 20.0° east of south

Use your knowledge of bearing, heading, and true course to sketch a diagram that will help you solve the problem.A plane has an airspeed of 185 miles per hour and a heading of 30.0°. The ground speed of the plane is 221 miles per hour, and its true course is in the direction of 40.0°. Find the speed and direction of the air currents, assuming they are constants. (Round your answers to one decimal place.)mi/hr at ° from due north

Use your knowledge of bearing, heading, and true course to sketch a diagram that will help you solve the problem.A plane is flying with an airspeed of 140 miles per hour and heading 150°. The wind currents are running at 30 miles per hour at 175° clockwise from due north. Use vectors to find the true course and ground speed of the plane. (Round your answers to the nearest ten for the speed and to the nearest whole number for the angle.)mi/hr with heading °
