Ah. I just realized that I can calculate average speed based on distance and average trip time. I'll do that tomorrow. Also, I'm debating whether or not trip time should be weighted.
If I drive for 100 miles in 100 minutes and then 10 miles in 10 minutes, is the average trip time:
unweighted 55 minutes = (100+10)/2
or
weighted 91 minutes = ((100*100+10*10)/110)
I think it's right to be weighted, but am not positive. What do you think?
