Thanks for the code.
1) But it is replacing my first names column.
2) I want only the integer value after the division. So instead of 4.9333 and 7.8333, I want 4, 7
3) The second calculated column ($2/($(NF-3)/60))} seems to wrong. For e.g. for the first row, it should be 20 and not 0 (101/(296/60)) for the second row, it should be 43 and not 0 (342/(470/60))
4) I get division by zero error if the column has 0:00. Is there any way to avoid this?

# awk -F"[ :]+" '{print $0" "$(NF-3)/60" "($2/($(NF-3)/60))}' myathar.txt
