Answer:
2 hours 29 minutes
Step-by-step explanation:
The difference in time is ...
(9 hours 17 minutes) - (6 hours 48 minutes)
= (9 - 6) hours (17 -48) minutes
= 3 hours -31 minutes
= 2 hours 29 minutes
_____
There are 60 minutes in an hour, so subtracting 31 minutes from an hour leaves 29 minutes.
