I would like to calculate the cost per minute. I have column with time,
hh:mm:ss, and a column with costs in swedish Krona. How do I divade the cost
with the time? I would like to know how much each minute of work costs.
Whatever I try the result ends up wrong.

The time is larger then 23:59:59 (i.e 133:25:00).

Appreciate any help!
