Calculating the Time

Time is an SY1 topic but the basics of the topic could be built on in SY2 and is one particular topic that is often used to make a complicated question, involving multiple Algorithms and Lateral Solutions because it is generally an easy topic, to get into your head.

To get your head around this topic think of the KS2/3 calculations involving time you did eg.what will the time be 999 minutes after 4:46 pm.These probelems can be summed up, in double digits with a gap in between eg.10 16 represents 10:16 am.Getting back to the original problem: 4 46= 16 46 999 minutes=16*60=960 so 16 39 so 16 46+ 16 39=32 85- add together minutes and hours then convert into proper from 32 85- 24 00=8 85=9 25- the hours have to be represented from 0-24 and the minutes 0-60.

For more complex calculations just convert the number into the amount of minutes then after all calculations are completed convert back into proper form, remember divide by 24*60 to get the number of days then forget about interger days and convert the fractional day into its equivalent form eg. 6 63 * 5 49- you aren't allowed to represent your answers in improper form but examiners are to confuse you or to make the equation harder. 6 63= 6*60 +63=423 5 49= 5*60 + 49=349 423*349=147627 147627/(24*60)=102.51875- ignore 102 days and focus on 0.51875*(24*60)=747 minutes= 12 27 so 6 63* 5 49=12 27- when dividing and producing non intergers write your answers in a suitable decimal form not hh mm ss, as this an entirely different continnuum.
