Answer:
12 hours and 4 minutes
Explanation:
To solve first convert both terms to minutes. Do this by multiplying the number of hours by 60, then adding the remaining minutes. 8*60=480, then 480+39=519 minutes. Next, convert 3 hours and 25 minutes to 205 minutes. So now we have 519 minutes and 205 minutes, so add those together to get 724 minutes. Finally, convert back to hours to 12 hours and 4 minutes by dividing by 60.
