    Loretta:

    Average driving speed = 55 mph

    Time = 4 hours

    Distance traveled = 55*4 = 220 miles

    Dad:

    Average driving speed = 65 mph

    Let x = hours driven

    Distance traveled = 65x miles

    The length of the trip is 610 miles, therefore

    65x + 220 = 610

    65x = 390

    x = 6 hours

    Answer: Loretta's dad drove for 6 hours.
