Answer: Total travel time is 4 hours.
Step-by-step explanation:
Since we have given that
Time at which he depart == 5:30 pm
Time when he arrive = 9:30
First we convert the time into standard time,
so, Departure time becomes
[tex]2130\ hours[/tex]
Arrival time becomes
[tex]1730\ hours[/tex]
So, Total travel time becomes
[tex]2130-1730\\\\=4\ hours[/tex]
Hence, Total travel time is 4 hours.
