Answer:
They arrived at 12pm.
Step-by-step explanation:
7:30am + 4 hours = 11:30am.
You still have 30 minutes left, so add those together.
11:30am + 30 minutes = 12pm.
the time when they left = 7:30 am
The interval of the trip on the train = 4hours 30 minutes
that can be written as 4:30
so 7:30+4:30 = 11:60 = 12:00(ans)
Hope it helps
