Here in the states they are called, highways.
That will depend on how fast you are driving and also on things like the quality of the roads, the weather and the amount of traffic.

depends on how fast the traffic is moving...if it is moving at 60 mph, it would take 12 mins...if they were moving at 30 mph is would take 24 mins...if they were moving at 15 mph it would take 48 mins...etc...
There is no simple answer to that. It would depend on things like how fast it is travelling, where it is going to and from, the quality of roads it is travelling, the amount of traffic on the road, the weather conditions, the type of bus, the amount of passengers and how many stops it has to make.
First, you need to know how fast the oncoming traffic is going. Obviously if traffic is moving slowly, you don't need a large gap. If traffic is moving fast, you need a larger gap. Secondly, you should know how long it will take you to speed up to the speed limit. Finally, if you are not sure if you can make it in a gap, don't try to. There will be another gap. The people who are behind you will wait. Be safe, be smart.
Because everyone is trying to pass the slower moving traffic and most highways are posted with the sign, "Slower traffic keep right" or the left lane (passing) is marked "Through Traffic".
A speedway is more commonly a stadium built for motor sports. It is also a road for fast-moving traffic.

That depends on how fast you are driving and things like weather conditions, quality of roads, traffic etc. So there is no real answer to the question.
The race cars usually go as fast as 100 miles per hour. Their speeds are usually not limited like in most of the commercial vehicles. The drivers drive this race cars very fast depending with the traffic and the type of roads.
