Every year around the Christmas period, Shaun and his church friends always go around carolling, at 7pm to 10pm each weekday night. If the group spends an hour for each house, inclusive of travelling time, and they started on Wednesday at 7pm, which day and at what time would they complete carolling for a street which contains 13 houses?
