What is the time 550 minutes after 22:15?
$begingroup$
i got this assignment where i need to answer what the time is 550 minutes after 22:15 but the minutes really confuses me.
I got a similar assignment where i had to calculate the time 10000 hours after 16:00 but here i just added the 16 hours to 10000 and looked at at the time 10016 hours after 00 using the residue class [10016]_24 which got me [8]_24 .
How can i do it similar on the first assignment?? We need to use residue classes.
