Calc Kill La Kill - Senjin Shippu

Ryuko and Satsuki chase after Ragyo at great speeds. This will more or less be straight forward. Go off the official height chart...
...and the unofficial scaling...
...Ryuko is estimated to be around 164cm tall (or 1.64m).
32 pixels = 1.64m
1 pixel = 1.64m/32 = 0.05125m
Timeframe is 2 frames.

0.05125m X 492 = 25.21500m

T = 1s/24
= 41.6666667ms X 2
= 83.3333334ms

T = 25.21500m/83.3333334ms
= 302.58m/s

Final Results
Ryuko & Satsuki fly after Ragyo = 302.58m/s
