959 miles divided by 70mph = 13.7 hours
332.5 miles (70 x 4.75 = 332.5).
it takes 17 and 1/7 hours
2.3 hours
Roughly 4 hours, 17 minutes, 8.5 seconds
maths. if you drive constant at 70MPH for 2 hours that's means 70 x 2 = 140 miles
20.4 hours
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.
