I believe you are asking how fast tornadoes can travel.
This varies. The average tornado moves at 35 miles per hour. Tornadoes may be stationary or may, in very rare cases, move at over 70 mph.
It depends on the car, but typically it takes a wind of at least 120 mph to lift a car. This is consistent with an EF2 tornado.
Air travels upwards rapidly in a tornado. If the speed of the updraft exceeds the terminal velocity of a person, then it can lift people off the ground.
The largest tornado on record in the U.S. varied in speed. For the early part of its time on the ground it traveled at about 30 mph before suddenly accelerating to 55 mph.
In most cases the wind speed of a tornado is estimated based on the severity of the damage it causes.
There is no solidly set minimum wind speed for a tornado. The Enhanced Fujita scale starts an EF0 at 65 mph, but tornadoes have occurred with estimated winds lower than that. Tornadoes are defined by the amnner in which the air moves rather than the wind speed. A tornado is a rotating vortex of strong wind that onnects to both the ground and the cloud base.
About 30 mph.

The tornado is reported to have had a path length of 27 miles and an average forward speed of 35 mph, which works out to a duration of 46 minutes.
At ground level, there is no intensity. At higher elevetions the intensity is less than after the tornado has touched down. When a tornado touches down, it is no longer able to draw in air from below. This causes the pressure in the core of the vortex to drop, leading to an increase in wind speed.
If you mean the one from April 27, 2011, the wind speed for that tornado was estimated at 205 mph (330 km/h), qualifying it as an EF5. Some have suggested, however, that the severe ground scouring caused by this tornado indicates winds far higher than 205 mph.
The wind speed of a tornado is inferred from the severity of the damage it inflicts.
The estimated wind speed of an EF0 tornado is 65-85 mph.
I assume you mean kilometers per hour as a kilometer is a unit of distance, not speed. Tornadoes vary greatly in speed. They may be stationary or travel at more than 100 km/h. A typical tornado travels at about 50 km/h.

No. A tornado is a violently rotating column of air the is in contact with both the ground and the cloud base. Violent winds alone do not make a tornado. A wind tunnel effect simply occurs when buildings or terrain funnel the wind to increase its speed.
In most cases the wind speed of a tornado is estimated based on the severity of the damage it causes.
