A student drove to the university from her home and noted that the odometer on her car increased by 13.0 km. The trip took 18.0 min.

(a) What was her average speed? 43km/h?

(b) If the straight-line distance from her home to the university is 10.3 km in a direction 25.0° south of east, what was her average velocity? 34km/h(25 S of E)

(c) If she returned home by the same path 7 h 30 min after she left, what were her average speed and velocity for the entire trip?

Average Speed = 3.5km/h?

Average Velocity = 0km/h?
