Average speeds

[99metro]

36-43mph over 55 miles for the tank.

38 in the backroads - no traffic
50-52 on the 65 mph zone

Average speed 186,000 miles per second - I telecommute :-)

I had to do some math for this one. 44.4 miles round trip and it usually takes 70 minutes. This means my average speed is 38.1 mph. Even though, a majority of my trip is on the interstate ranging between 65 and 80 (down hill) mph. This is without any figures for the fact that I carpool with another person.

25 miles each way, 30-35 minutes depending on traffic.

This thread has given me an idea regarding my fuel logs. My truck's overhead console will record vehicle on time (not sure if it's engine-on or ignition-on, my bet's on ignition) and I have been resetting it at every fill-up without logging the time. I'm starting to log the time which will compute a tank-average speed. I have already noticed that up to a point I get better mileage with a shorter run time. Much shorter than 9 hours appears to level out or decrease mileage as it would mean all-highway/high-speed driving. This tank was rather long...not many tanks come close to 11 hours let alone going past 11. I'm logging the run time and the calculated average speed in the fuel log comment section.

I generally get a tank average speed of about 30mph. Most of my driving is on 55mph speed limit streets with very few stop signs, with a little city driving thrown in. I try to EOC whenever possible, which is why the avg speed is so low.
