I need formula help; and as I know this board has a group of some of the smartest (and smart ass) people I know...

I need a formula for figuring out MPH (miles per hour) dealing with: fraction of miles and minutes/seconds.

For example:

1.25 miles in 11 minutes and 23 seconds.

What is that in MPH? And what does the formula look like for paper/pencil...as well as how would it look as a formula in a spreadsheet cell?

I'm having, well, a hard time even doing that by hand. I must be "missing" something that simplifies it. I found a website that does it for me...but I want that knowledge

Easiest is to convert the time into hours with decimals (ie. hour=min/60+sec/3600) and then just do distance/hour.
The new Mac Pro has up to 30 MB of cache inside the processor itself. That's more than the HD in my first Mac. Somehow I'm still running out of space.

If you want it easier than that: Wolfram Alpha:

1.25 miles in 11 min and 23 sec in MPH - Wolfram|Alpha

Like I posted: I already found websites to do it. What I wanted was how to do it myself in my own spreadsheets...and that was already answered.

MacNN never fails to deliver...
