So about 5.5 - 6.5 hours of meetings over 2 weeks. If you're really militant, you can probably take it down to 4 hours, but I don't think you can get much lower than that without dispensing with formal Scrum.
It doesn't seem unreasonable to me to have 6.5 hours of meetings over 2 weeks.
Daily standup: 15 mins x 10 days = 150 minutes = 2.5 hours Backlog grooming: 0.5 - 1 hour Sprint planning: 0.5 - 1 hour Retrospective: 1 hour Demo: 1 hour
