25 minutes + 8 hours = 8 hours 25 minutes
8 hours 25 minutes + 20 hours 10 minutes = 28 hours 35 minutes
Therefore, 25 minutes + 8 hours + 20 hours 10 minutes = 28 hours 35 minutes.
25 minutes + 8 hours = 8 hours 25 minutes
8 hours 25 minutes + 20 hours 10 minutes = 28 hours 35 minutes
Therefore, 25 minutes + 8 hours + 20 hours 10 minutes = 28 hours 35 minutes.
