You either drive as fast and carefully away from the tornado, or if there is a tornado shelter nearby, hide in it. Don't go under a bridge or overpass since these act as windtunnels.

How fast a tornado is moving refers to how fast the tornado itself travels from point A to point B. For example, a tornado moving towards at 30 mph and is a mile away will reach you in 2 minutes. The rotational winds of a tornado refers to how fast the tornado itself is spinning, which is generally faster than its forward speed.
It varies widely. A typical tornado travels at between 30 and 40 mph, but some tornadoes are stationary, while others can travel at over 70 mph.
