To find the estimated arrival time, we need to add the travel time of 4 hours and 44 minutes to the departure time of 9:33 a.m.
First, let's convert the departure time to minutes:
9:33 a.m. = 9 x 60 + 33 = 573 minutes
Now we can add the travel time:
573 + 4 x 60 + 44 = 819 minutes
Finally, we can convert the total minutes back to hours and minutes:
819 minutes = 13 hours and 39 minutes
Therefore, the estimated arrival time is 11:12 p.m.
