I will appreciate aaany help regards

Answer 1

If you need to analyze your data more than creating a static function to count, you may consider using Pivot tables.

Build a simple pivot table with age in rows and time in values. Once this simple pivot table built, you can filter on the rows values, group them together among specific grouping criteria, select specific values by hand, etc.

Answer 2

I like the idea given by Boud of using Pivots but if you specifically want a formula then you can use SumProduct()

=SUMPRODUCT((A2:A13>16)*(A2:A13<40)*(B2:B13))

Do remember to format the cell as [h]:mm:ss since you are adding up times.

Answer 3

You can for example add additional column, with formula like:

=IF ( AND(A1>16, A1<40), B1, 0 )

where A is column with AGE, and B is column with Time, and then simply sum it!
