the answer is about up my but and around the corner :p
At an average 30 mph, it would take one hour.
At 60 MPH average, about 30 hours.
It depends on your average speed. At 60 mph, you can drive 600 miles in ten hours. At 30 mph, it will take you 20 hours.
How fast will you be driving? At 60 mph it will take 30 min. At 30 mph it will take 1 hour.
450 mi / 30 MPH = 15 hours
30 hours 46 minutes.
At 60 MPH average, about 1 hr 18 min.
To cover the 851 miles from London to Cannes will require at least 8 hours and 30 minutes of driving time at an average of 100 mph.
It would take 30 minutes driving at 30 MPH.
1 hour.
35 feet at 30 mph requires about 0.8 seconds.
30 mi / 550 mph = .054 hr = 3.27 min.
