You are in a car for a ride, and take the following course:
50 km/h for 2.0 min, turn 90 degrees to the right, 20 km/h for 4.0 min, turn 90 degrees to the right, 20 km/h for 60 seconds (1.0 min), turn 90 degrees to the left, 50 km/h for 60 seconds (1.0 min), turn 90 degrees to the right, 20 km/h for 2.0 min, turn 90 degrees to the left, 50 km/h for 30 seconds (0.5 min).
At this point, how far are you from your starting point? Also, in what direction relative to your initial direction of travel are you?

Create a diagram with scale distances and then draw a line from the endpoint to the starting point and you should have a triangle. Use trigonometry to figure out the distance and the angle.

Assuming you started out heading east.
You travelled 1.6 km E, 1.3 km S, .3 km W, .83 km S, .6 km W and .416 km S
This results in .66 E, 2.583 S
You are 2.67 km from the starting point heading 90 degrees to the right (South)
