Question

56. What time will it be 46 hours after 9:30 p.m.

Answer 1

The time will be 2 hours short of 48 hours( equivalent to 2 days)
So,
9.30 pm on Friday + 48 hours it will be;
9.30 pm on Sunday
Then subtract two hours;
9.30 pm- 2hours
Sunday, 7.30 Pm

Answer 2

46 hours after 9:30 p.m. on Friday will be J. 7:30 p.m. Sunday. 
Since 46 hours is almost two days, you just need to take away those two hours, and you will get the time you need, two days after the original day.
