The ranger starts at the ranger station and walks 4 km [N 30° W] in 1.5 hours and then changes direction to cover 9km [ E] in 2.50 hours before finding the lost hiker. Find the hiker's displacement from the ranger station so they can call back to the station for rescue. Don't forget to tell them exactly what direction to head! You may solve using any method (scale diagram, trig, or horizontal & vertical components) - in all cases you must include a labeled VECTOR sketch. Determine:
