A day has 24 hours, so if you add 23 hours, you are going 1 hour less than a full day. When you are ignoring what day it is, it appears to just be moving back one hour. Therefore, the answer is 7:00 pm. Comment if you have any questions!
It would 9x+20 because u have to distribute
6*15=90 it will move 90' in 15 min. and in a full hour it will 360'
