Sure, no problem.
In your template, I take column K and label it Start Time, column L ist End Time, column M is Duration and column N ist Avg Speed. I define the data cells in column K and L as "time", and column M and N as regular numbers.
In K and L you just put in the times in a regular hour format, like 12:15.
Column M is "=24*(L7-K7)" - that gives you the time in hours.
Column N is "=J7
/M7", giving you the average speed in mph or kph, whatever you use.
Average MPG and cost is more difficult, but there should be templates for that available online.
Samson was a biblical tough guy, but his dad Samsonite was even more of a hard case.
