My sister perlita, lives in anacortes Washington, U.S.A in what time will she meet me in online chatting if I chatting if I chat at 8:00 pm here in manila



Answer :

I'll assume you are referring to Manila, Philippines. This city is given the time zone GMT+8 meaning that you are 8 hours ahead of Greenwich Mean Time (GMT).

Anacortes, Washington (in the United States) is meanwhile assigned the time zone code of GMT-7. Normally it is GMT-8, but we add 1 hour due to Daylight Savings Time (DST). The negative indicates your sister is 7 hours behind GMT.

Draw out a number line. Mark -7 and 8 on the number line. Then notice there are 15 spaces between the values. Or you can subtract and use absolute value.

|p-q| = |-7-8| = 15 where p = -7 is the GMT value for Anacortes and q = 8 is the GMT value for Manila.

--------------------------------------------------------------------------

So all of that previous paragraph boils down to this: there's a 15 hour gap between you and your sister.

Notice how 15 hours is 3 hours longer than 12 hours because 15-12 = 3.

This means that to quickly find your sister's time, you will subtract 3 from your local time and swap AM to PM, or vice versa.

Examples:

  • It is currently 8:00 PM in Manila. Therefore it is 5:00 AM in Anacortes because 8-3 = 5, and the PM swapped to AM.
  • Another example: It is currently 6:00 AM in Manila. Subtract off 3 and swap AM to PM to determine it is 3:00 PM in Anacortes.

Reverse this process to determine what time it is in Manila if you know the time in Anacortes.

Answer is 5:00 AM
