km/h
(B) If the straight-line distance from her home to the college is 11.8 km in a direction 20.0° south of east, what was her average velocity? State your answer in km/h.
average velocity =
km/h at south of east
(C) If she returned home by the same path 10 h 45 min after she left, what was her average speed for the entire trip? State your answer in km/h.
average speed =
km/h
(D) If she returned home by the same path 10 h 45 min after she left, what was her average velocity for the entire trip? State your answer in km/h.
average velocity = km/h
