Intro
In chapter 30 of naruto, Kakashi charges at Zabuza with the Raikiri in order to kill him. The attack however is intercepted by Haku and ends up killing him instead. I will be calcing the speed of kakashi from this encounter

Calc
To start we need to find the distance between Zabuza and Kakashi (distance kakashi moved)

According to the wiki, Zabuza is 1.83 meters tall.

In this panel zabuza = 124 px = 1.83 m

Distance between the two is 326 px = 4.81112903226 m

Now that we have the  distance we need to find the timeframe.

In this panel after the attack we see naruto in the standing in the same spot where Haku started moving. So we'll us this as the distance traveled.

We can see Zabuzas outline in the distance, so zabuza= 35 px = 1.83 m

panel height = 387 px

2atan(tan(70/2)*(35/387))= 7.2469782439 degrees

plugging it into the angsize calculator = 14.449 m

Now to find the speed, which is simple since the Ice mirror is confirmed light speed

Using the fromula Time = distance/speed we get...

T= 14.449/299792458 (speed of light in m/s) = 0.0000000481966761 seconds

Now that we have both our distance and time we can solve Speed = distance/time

S= 4.81112903226/0.0000000481966761 = 0.3329731492681514 c

Final Tally
Kakashi charges at Zabuza and kills Haku

'''0.3329731492681514 c

(Relatavistic)

33% the Speed of light'''
