Could you explain the work please, I really wanna know how to do this. I have a test coming:(... It's completely different from regular addition. Im homeschooled btw.

Answer 2

add the seconds, if they are more than 60, then divide it by 60,quotient is minutes and remainder is seconds.
above sum of seconds is 65 ,divide it by 60 ,1 is minute and 5 are seconds.
similarly for minutes.
Remember 1 minute=60 seconds
1 degree=60 minutes.
