A minimum of 15.7 hours.
Just under 13 hours 13 x 85 = 1,105
12 hours 56 minutes.
18 hours 20 minutes @60 mph
11 hours 3 minutes at 60 mph
2 hours 16 minutes.
It wil take 18 1/3 hours to drive 1100 miles at 60mph. I figured this out by this formula: D=R*T, in which D=Distance,R=Rate, and T=Time. Then i just plugged in the numbers, D=1100 miles,R=60mph,and T=x, because the time is unknown. So this should look like this: 1100=60*T 1100=60x 1100/60=18.3 or 18 1/3 hours/
30 minutes (mph= miles per hour)
It takes five and a half hours to drive 253 miles at 46 mph.
7 hours to drive 420 miles going 60 mph.
It would take 12 minutes to drive 20 miles at 100 mph.
If you drove non-stop at a constant speed of 75 mph, it would take about 14 hours and 40 minutes.
