Heres the question - how would/do you teach a child to calculate elapsed time?
Remember the method had to be applied to all time calculations - no exceptions to the rule
Say for example to calculate elapsed time from 1.13pm to 5.42pm
1.13 to 1.22 = 9 minutes
1.22 to 1.42 = 20 minutes
1.42 to 5.42 = 4 hours
Total = 4 hours and 29 minutes
This method is constant and applied to all time calculations and Mr 11 cannot grasp this.
Is there an easy consistent method of calculation of elapsed time?
