After inviting about 30 jedi to their sandwich party, Yoda and Obi-Wan were exhausted hosting the party.
It turned out Obi-Wan needed 1 hour and 30 minutes to clean the kitchen (he thought he could do it in 1 hour and 20 minutes!). Yoda could do it in 1

How much time would Yoda need to clean the kitchen?
