Mrs. Smith took 4 days to decorate the house for Christmas. She spent each day working from 1:00 pm to 2:30 pm. She took 2 days to put up the Christmas tree, working each day from 2:20 pm to 3:30 pm. She spent twice the amount of time shopping for Christmas presents than putting up the Christmas tree. How much time did she spend altogether on decorating the house, putting up the Christmas tree, and Christmas shopping?
