Sorry for my lack of terminology here but I need help to accomplish the
following:

From cells containing time in format 0:12, 1:18 etc, meaning 12 minutes
and one hour and 18 minutes converting it according to:

1-6 minutes = 0.1
7-12 minutes = 0.2
13-18 minutes = 0.3
19-24 minutes = 0.4
25-30 minutes = 0.5
31-36 minutes = 0.6
37-42 minutes = 0.7
43-48 minutes = 0.8
49-54 minutes = 0.9
55-60 minutes = 1.0
61-66 minutes = 1.1 etc etc...

That is, rounding and displaying as 10th's of the hour depending on how
many minutes there are in the input cell.

Any ready-to-use formula or vba-script would be greatly appreciated! :)
