Excel Formula minutes convert to hours

I formatted the cell to "Time" and display hh:mm

Then when you "SUM" the column, the math is correct.

to get the totals to total a large number of hours.. like 310:20 (310 hrs
20 minutes) log book total.. you will need to pick the hh:mm:ss format. the
display will now read 310:20:00

Hi does anyone know the formula for excel so it will add the minutes after
the decimal and convert them to hours.

Need to check my log book times and make a database off information types
flown etc.

EG

1.33
1.56
=2.89

Needs to say 60 mins is one hour

so

1.33
1.56
=3.29

???????????????

=SUM(E1:E23)

=IF(A31000,TIMEVALUE(LEFT(A3,1)&":"&RIGHT(A3,2)),T IMEVALUE(LEFT(A3,2)&":"&RIGHT(A3,2)))
The formatting of the cells in column B is HH:MM.

Thanks Mal
