Hi, I had an SAT question of the day that I cannot figure out. The question is:
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.)
The answer choices are:
1. 5:00 a.m. Saturday
2. 1:00 a.m. Sunday
3. 5:00 p.m. Tuesday
4. 1:00 a.m. Wednesday
5. 5:00 a.m. Wednesday

  • math -

    240 hours is ten days ahead (4 PM Tuesday). Add 13 hours to that and you get 5 AM Wednesday.

  • math -

    Since each day has 24 hours, it is a good idea to divide 253 by 24 to find the number of complete 24-hour intervals in 253 hours and the number of hours remaining after the 24-hour intervals have been accounted for. When 253 is divided by 24, the quotient is 10 and the remainder is 13. The 10 complete 24-hour 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.
