Question 107313
Add all of the categories separately. 
Hours : {{{4+3+7=14}}}
Minutes : {{{17+58+45+12=132}}}
Since the number of minutes is greater than 60 (60 minutes=1 hour),
you can simplify.
2 hours would be 120 minutes. 
132 minutes = 2 hours 12 minutes. 
Hours : {{{14+2}}}
Minutes : {{{12}}}
Now add everything together.
16 hours 12 minutes.
