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.
