If it is now 4:00 p.m. Saturday, in 253 hours from now, what time and day will it be? (Assume no daylight saving time changes in the period.)
(A) 5:00 a.m. Saturday
(B) 1:00 a.m. Sunday
(C) 5:00 p.m. Tuesday
(D) 1:00 a.m. Wednesday
(E) 5:00 a.m. Wednesday
The Correct answer is E.
Explanation
Since each day has 24 hours, divide 253 by 24 to find the number of complete 24-hours intervals in 253 hours and the number of hours remaining after the 24-hours intervals have been accounted for. When 253 is divided by 24, the quotient is 10 and the remainder is 13. The 10 complete 24-hours intervals tell you that 10 days, or one full week plus 3 days, go by, bringing you to Tuesday at 4:00 p.m. The 13 additional hours take you into the next day, Wednesday. The 253 hours will end at 5:00 a.m. on Wednesday.
