App for calculating when to leave to arrive at a certain time

That’s my go to.

 

Another person already said this but I did long trips the same way. Divide total miles by 25mph. So if you have 2500 miles/ 25 mph you will need 100 hours. That just a little more the 4 days, 100 hours/ 24 hours in a day is 4.16 days.

If you're wondering were the 25 mph come from. If you can drive 600 miles a day/24 hours in 1 day is average speed of 25mph. If you want to drives 500 miles a day. 500/24 is 20.8 mph average will call it 21. So 2500 miles /21 mph would be, 119 hours.

119/ 24 hours is 4.95 so basically 5 days if you drive 500 miles a day or 4 days if you drive 600 miles a day.

 

Bad weather, like heavy snow, I add 50% travel time. Might sound like overkill, but I find it’s often realistic. 50 mph average can often be beat, in good weather, with the higher speed limit now. All the more reason to use 50 mph average. Assures being on time. Keeps it simple that way. Mileage 800x2=16 hrs. Add a 10 hr break= 26 hrs travel time. 300 x 2= 6 hrs. 250x2=5hrs. No need to even use a calculator.

 

I have my own system but I always like to see if I can improve on it. I was okay up until your last two sentences. Can you explain it? Thanks.

 

It's exactly what @slow.rider does here -

 

LOL. I see. That's exactly what I do, multiply by 2 and then add a 10-hour break for every 11 hours of drive time. I didn't read the last two sentences clearly. I thought they were part of the same calculations, not separate ones! Coffee time.

 

Do you run at night or during the day?

 

This combination has been working well for me. View attachment 377166 View attachment 377167

 

Trip miles say 1378.
Average speed 50mph
1378/50=Roughly 28hrs.

Don’t over think it man.

 

That's just DRIVE TIME. Also, much easier to multiply by 2 than divide by 50.
