maths. if you drive constant at 70MPH for 2 hours that's means 70 x 2 = 140 miles
average speed of 70mph it will take 4 hours. obviously legally 70mph average speed is impossible to do. so for a genral trip of 280 miles from experience takes about 5 hours. this obviously varies depending on the roads you are taking... time of day.... traffic... etc.

It will take about 9 hours and 46 minutes of total driving time at a constant 70 mph. Add some time for stops and delays.
