Not necessarily. Officially, winds for an EF0 tornado start at 65 mph, and some tornadoes in recent years have been rated with winds as low as 55 mph. This is still sufficient damage trees and some weak structures.
By definition, a hurricane must have sustained winds of at least 74 mph.
10 to 20 mph would be a slow moving tornado. A typical tornado travels at 30-35 mph.
1 in 9 ? in 60 Cross multiply and you will get 6.6666.
On the Ehnahnced Fujita scale, 200 mph is a borderline EF4/EF5 tornado.
Wind estimates for an F2 tornado on the original Fujita scale are 113-157 mph. This was later found to be inaccurate and was changed to 111-135 mph for an EF2 tornado.
The weakest wind speed of a tornado is typically around 65 miles per hour (105 kilometers per hour), which is considered an EF0 tornado on the Enhanced Fujita scale. These tornadoes are the least destructive and usually result in minor damage.
In excess of 200 mph at the peak, possibly as high as 250 mph.
By the standards of the Enhanced Fujita scale the minimum wind speed for an EF0 tornado is 65 mph. However, simply having a wind at or above this intensity is not enough for there to be a tornado. A tornado is a violently rotating vortex of wind, not just a gust above a certain strength.
The Veyron can reach at least 253 miles per hour.
miles per hour = mph
If you mean wind speed, winds can range from 65 mph to over 300 mph, though most tornadoes have winds in the range of 65-85 mph. The most destructive tornadoes have winds over 135 mph. Winds over 200mph are extremely rare. The forwards traveling speed of a tornado can range from 0 mph to 73 mph (the record so far). The average tornado moves at 35 mph.
There is no such thing as an E4 tornado. An EF4 tornado has peak estimated winds of 166-200 mph. In some cases, however a tornado rated EF4 may have been capable of producing EF5 damage (winds over 200 mph) but did not impact any structures that culd yield an EF5 rating.
Tornadoes can move at speeds of up to 70 miles per hour (113 km/h) or even faster in extreme cases. The speed of a tornado can vary greatly depending on its size, intensity, and the surrounding atmospheric conditions.
