Refer to the diagram shown below.
The resultant displacement, d, is the vector sum of distances traveled west and south.
The magnitude of d is
d = √(25² + 35²) = 43.012 km
The angle that d makes below due west (or south of west) s
θ = tan⁻¹ (35/25) = 54.5°
Answer:
The resultant displacement is 43.0 km, at an angle of 54.5° south relative to due west.
