Well it depends on what type of global Jet stream,
1.Polar- Much stronger but not as fast as the other jet streams traveling at 8-12km per hour.
2.Sub-Tropical- Not as strong as polar but goes 10-16km per hour
3. Equatorial_ weakest of the 3 but winds at 13-19km per hour

What is isotachs contours?
These are lines of equal wind speed. They are most often contoured in the upper levels of the atmosphere, especially at the jet stream level. They are important for locating the jet stream and jet streaks within a jet stream
