Most US states have an interstate speed limit of 70 mph however most western states have a 75 mph speed limit on interstates and most northeastern states have a 65 mph maximum interstate speed limit.
Keep in mind: average speed is not max speed. In practice, over a longer trip, the average speed is much lower than the max allowed one because of traffic, driver inconsistency, stops, etc.
If your car has a trip computer: most show average and maximum speed, but even if they only show one speed (the average one) you can easily test for yourself. Reset the trip computer (or GPS trip) and look at the average speed after a meaningful distance. Keeping an occasional eye on the speedometer (your eyes should be on the road ahead!) will show you that your average speed is less than your maximum speed right away.
depends if your on the road or flying lets asume that your flying there is no speed limit
