What Is The Formula For Calculating The Duration Of A Trip?

Beginning Monday, I will be traveling by car from Portland to Atlanta. My ELD is here. I'm having trouble calculating how long it will take me to get there. How do you all manage?

Which formula or method do you employ?

50mph x 10hrs is 500 miles minimum a day. In a car u can make much better time. Faster and can drive longer. A GPS often calculates it for u. Loaded truck weight will slow us down on hills/mountains.

Also, if/when you get a truck GPS be careful what you have the maximum speed set at in settings. I leave mine set pretty conservatively (set at 67 mph but my truck goes 70 mph) as a buffer against HOS violations.

In general however, don't get in the habit of blindly following the GPS for your time to destination OR directions in general. Your GPS is not your brain, the GPS is a very fallible but often useful tool.

Best of success on your trip!

If you're using it to practice, a good basis is Weight and Weather, they determine your route which then determines your rate of travel which then determines your stopping point.

For example, a 44k lb load, 79k gross) going from Cheyenne wy to Cedar Rapids IA, no thunder storms but winds gusting to 38 mph. Meaning you'll be ok to take I80 inspite of the winds.

Trip is 750 miles, mostly flat interstate. You might average 55 mph with stops, etc. Set your target at 550 miles, or 10 hours of driving/on duty as you have full clocks. The second day will be 250 miles to reciever.

That means you need to have 3 or 4 places to shutdown around Omaha NE, being 500 miles from Cheyenne. If need be, you can push it a little bit, but safely shut down for the night around the 500 miles mark.
