  1. assuming that he reads for 25 min and rests for 5 min,

    he reads 9(25/15) = 15 pages every half hour

    198/15 = 13 remainder 3

    so, he reads for 13 half-hours = 6:30
    plus an extra :05 for the last 3 pages.

    8:00 + 6:35 = 2:35 pm

    Note that if the 5-min break occurs during the first 3 minutes of the half-hour, his end time will be increased by 5 minutes to 2:40 pm
