The time difference between the UK and Cyprus is +2 hours GMT.
You are flying from Birmingham and it takes 4 hours 20 mins to get to Larnaca in Cyprus. If you leave at 11:45, what time will you arrive? (if it runs on time, that is.)
Remember, when adding and subtracting minutes we do not always use base 10
To add on 3 hours 45 minutes to 15:25 the sum would look like this.
To take away 3 hours 45 minutes from 15:25 the sum would look like this.
As there are only 60 minutes in an hour, the 'tens' column of the minutes is in base 6. Base 6 counts as: 1,2,3,4,5, 10, 11 etc. Therefore, 2 + 4 + the carried 1 = 11. .
Because there is only 2 in the 'tens' column of the minutes, we borrow from the hours column. Because that hour is now minutes, and therefore in base 6, you add 6 to the 2, so that column now has 8. Got that?
