I bike race and like to keep track of average speed of the races. I'd like
to set up a template in Excel that I can easily enter the time and distance
and let the spreadsheet do the figuring. I have a template now, but have to
enter many different numbers to convert the time to decimal numbers and the
formulas are long and cumbersome.

If you have the miles biked in column A starting with A2 and the time
for each distance in B, then in C2 enter =SUM($A$2:A2)/SUM($B$2:B2)/24.
Drag this down column C for as many races as you have. It gives the
unweighted average for all races in rows 2:n.
