If the time is currently 1:30 pm, what time will it be in exactly 647 hours? A. 12:30 am B. 1:30 am C. 12:30 pm D. 2:30 pm E. 10:30 pm
(C) If we divide 647 by 24, not arriving at a decimal, but rather keeping the answer in terms of an integer and the remainder, this number will represent the number of days and hours later that 647 hours is: 647/24 = 26, remainder 23. Therefore, 647 hours from now is the same as 26 days and 23 hours from now.
The time will be exactly 1 hour earlier in the day, so it will be 12:30 pm. The correct answer is choice (C). --------- It is currently 1:30 pm, which is the same time as 13:30 am. Add 23 hours and one gets 12:30am. Answer A.
