    Answer:

    The time taken is missing in the question. The time is 18 minutes.

    The answer is 34.3 km/hr

    Explanation:

    Average velocity is the speed or the velocity which is required to cover a distance in a time interval.

    The time taken is = 18 min

                                = 18/60 hours

    The distance from the university to her home is = 10.3 km

    Therefore, the average velocity is = displacement/time taken

                                                             = 10.3 / (18/60) km/hr

                                                             = 34.3 km/hr

    Hence, the average velocity is 34.3 km/hr
