Have searched a lot of excel sites, and have yet to come up with an answer to this time problem.
Here are two examples...
I worked 4 hours and 15 minutes and finished 67 units. How many minutes did it take to do each unit?
or I worked 4 hours 5 minutes and finished 57 units. How many minutes did it take to do each unit?

As you can see, I am trying to covert time to not time, back to time (does that make sense?)
Any help would be great appreciated. Have been trying to tackle this one, and just can't figure it out.
Thanks in advance,
Beards
