Mach 2.5
it is f15
The f-15 eagle fighter jet can fly at 1875 miles per hour or [mach 2.5 plus].
impossible to tell because every jet is different
At high altitudes the F-15 can do Mach 2.5+ (1,650+ mph) at low altitudes it can go Mach 1.2 (900mph).
Knots per second squared is not a unit of acceleration.
I think they can fly pretty fast.
humming birds fly so fast because they are so fast
fast
F15
As fast as you can throw them ;)
Fast enough.
