Answer:
A.60 Minutes/1 Hour
Explanation:
New Year's Eve = December 31st
They started playing at 6:00 pm till 2 January 9:00 am
So, till 1st January 6:00 pm they played for 24.
From 1st January 6:00 pm to 2nd January 6:00 am they played for 12 hours
From 6:00 am to 9:00 pm on 2nd January they played for 3 hours
So, total time they played = 24+12+3 = 39 hours
Converting to minutes

So, 60 Minutes/1 Hour conversion ratio should be used.
