Vacational Bonus

Two questions from The Mensa Genius Quiz-A-Day Book. Answer both correctly for a bonus point.

My husband and I can't seem to get our watches to work properly. His consistently runs one minute per hour fast, and mine runs two minutes per hour slow. This morning we nearly missed a wedding because our watches were an hour apart and we looked at the slower one. How many hours had elapsed since we set both of them properly?

AND

Cressida didn't like to tell her age, so when she was asked, her mother answered for her. Her mother said, "I'm just seven times as old as she is now. In twenty years, she'll be just half the age that I will be then." How old is little Cressida?
