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.
extreme tornadoes can attain wind speeds of more than 300 mph (480 km/h)
The forward speed of a tornado varies, but most will travel at about 45 to 55 km/h. However some tornadoes are nearly stationary while others may move at over 110 km/h. The winds inside a tornado can range from about 100 km/h to about 480 km/h, though most do not exceed 180 km/h.
at a speed of about 350 km/h
A Tornado GR4 has a maximum speed of 800 knots (1,482 km/h, 921 mph)
about 7 hours depending how fast you travel
approximately 13 km/hour
It depends on where in space they are but they often travel extremely fast, upwards of 11 km per second
Spicules travel at about 20 km/s (72,000 km/h, 45,000 mph)
About 30 km/second.
300000 km/second
2,400 km per hour
about 310 km per hour
