That depends on the speed. Pick a speed, then divide the distance by the speed. If you divide a distance in miles, by a speed in miles/hour, the answer will be in hours.
Six hours.

That depends how many hours you travel at that speed.
To find out how many miles you have driven, you can use the formula: Distance = Speed × Time Given that you're traveling between 35 to 50 miles per hour and you've driven for 68.1 hours, we'll calculate the distance for both the minimum and maximum speeds: For minimum speed (35 miles per hour): Distance = 35 miles/hour × 68.1 hours For maximum speed (50 miles per hour): Distance = 50 miles/hour × 68.1 hours Let's calculate: For minimum speed: Distance = 35 miles/hour × 68.1 hours = 2383.5 miles For maximum speed: Distance = 50 miles/hour × 68.1 hours = 3405 miles So, you have driven between 2383.5 miles and 3405 miles, depending on whether you were traveling at the minimum or maximum speed.
3.5 hours.

It depends on the speed. Find a calculator online, and divide 878 miles by the speed in miles per hour.
The time it takes to drive 20 miles depends on the speed at which you are driving. If you are driving at a constant speed of 40 miles per hour, it would take you 0.5 hours to drive 20 miles (20 miles / 40 miles per hour = 0.5 hours). If you are driving at a constant speed of 60 miles per hour, it would take you 0.33 hours to drive 20 miles (20 miles / 60 miles per hour = 0.33 hours).
Just divide the distance by the speed. If the distance is in miles, and the speed in miles/hour, the time will be in hours - which you can then easily convert to days.
