1800 Miles if he was back in the old days and left at Midnight Monday Morning you ran 10 Slept 8 got up and ran for another 10 meaning you Drove over 15 hours in one day. DO that 2 days in a row and you can rack up the miles. Do not ask me how I know this aka Salinas CA to Salem IL in 44 Legal as Hell. He would only need 30 hours of Drive time to make it in 2 days it can me DONE.
Actually I was at first,lol.But redid the math and edited my post.Thats easy as pie to make that run, just don't have time to do anything else but drive and sleep.
That's 67 miles an hour. From Monday morning to Wednesday afternoon is more than 48 hours, not 27. Sorry. I see you corrected your math.
First day was El Paso to the truck parking area near Cumby, TX on I 30. About 693 miles. Second day was up to the rest area on I 65 north of Horse Cave, KY. About 700 miles. Final stretch was about 441 miles to the customer. Averaged about 64 mph.
