Thank you for the opportunity to help you with your question!

60*12hrs=720minutes

angle of hand turn in 20 minutes=20/720*360=10degrees

distance traveled by the minute hand in this turn=60/5*20=1.66cm

the magnitude of the displacement vector of the minute hand in the period.=2cm


Please let me know if you need any clarification. I'm always happy to answer your questions.
