Answer: 5:40 am
Step-by-step explanation:
The train reached the station at 9:15 am after having travelled for 3 hrs 35 minutes.
The time the train departed from Riya's hometown was the time it arrived in Mumbai station less the time taken to travel:
= 9:15 - 3:35
First deduct the 3 hours:
= 9:15 - 3
= 6 : 15 am
Remove the 35 minutes by first removing the 15 minutes
= 6:15 - 15
= 6:00 am
Then remove the rest of the 35 minutes which is 20 minutes:
= 6:00 - 20 minutes
= 5:40 am
