10 1/2 hrs with no stop
Your 469 mile journey at 45 mph would take approximately 10 hours and 26 minutes (non stop driving)
Non-stop at 65 mph would take 10 hours 13 minutes 51 seconds.
If you drive non-stop at a constant speed of 65 mph, it will take about 10 hours and 26 minutes.
It would take about 7.16 hrs which is about 7 hrs 10 minutes as long as you didn't stop and stayed at a constant speed.
It would take 8 minutes non-stop, at a constant 80 MPH. However, this is unrealistic in any traffic situation. If you stop once for gas (10-15) minutes and once to eat (60-90 minutes) it could take as long as 2 hours. Actually in 80 mph nonstop it will take about 4.5 mins.
7 miles / 10 mph = 7/10 hour, or 42 minutes
About 1 minute 8 seconds at a constant 10 mph.
About 10 minutes at 65 mph
10 Minutes 6 mph= 1 Mile every 10 Minutes
It will take 20 min to go 20 miles at 60 mph.
40/10 = 4 hours
