Stocking runs all around the planet to different countries before finally running into outer space. Even though there's a transition between each place, we can still see how fast Stockings is running in space through the movements of the Earth.
R = (h/2) + c^2/(8h)
= (67/2) + 789^2/(8 X 67)
= 1194.91978
Radius of the Earth is 6378.1km
1194.91978 pixels = 6378.1km
1 pixel = 6378.1km/1194.91978 = 5.33768049km
5.33768049km X 264 = 1409.14765km
1 pixel = 1409.14765km/138 = 10.2112149km
10.2112149km X 28 = 285.914017km
10.2112149km X 137 = 1398.93644km
1398.93644km - 285.914017km = 1113.02242km
T = 1s/25
= 40ms X 17
= 0.68s
T = 1113.02242km/0.68s
= 1636797.68/340.29
= Mach 4810.00817
Lastly for KE. Stocking has no official weight, but she takes the form of a girl between 17 and 19 according to the Panty & Stocking wiki, so we'll just go with the higher average of 120 lbs for 17 year old girls (or 54.4311kg).
E = (0.5) X 54.4311 X 1636797.68^2
= 7.29133609e13
= 17.426711496175908 kilotons
Final Results
Stocking runs into space (speed) = Mach 4810.008
Stocking runs into space (energy) = 17.427 kilotons
