Alright, lets get started.
[tex] t_{i} = 11:31 am [/tex]
[tex] t_{f} = 8:22 pm [/tex]
We need to find elapsed time between 11:31 am and 8:22 pm.
From 11:31 am, it will first go to 12:00 pm then 8:22 pm.
So, time elapsed from 11:31 am to 12:00 pm :
[tex] 12:00 - 11:31 = 0 : 29 [/tex]
time elapsed from 12:00 pm to 8:22 pm : 8:22
So total time elapsed : [tex] 0:29 + 8 :22 [/tex]
So total time elapsed : 8 : 51 : Answer
Hope it will help :)
