6 hours 55 minutes.
5 hours 37 minutes.
450 miles.
6 hours 55 minutes averaging 65 mph
450 mi / 30 MPH = 15 hours
450/60 = 7.57.5 hours
Seven and a half hours.
7 hours 30 minutes.
Time = Distance/Speed. So, in the unlikely event that you can maintain an average speed of 65 mph, it would take 450/65 = 6.92 hours = 6 hours and 55 minutes approx.
