My very first clac. Pretty simple and straightforward so let's get on with it.

In the above video, Ying runs 1000 km in a short timeframe to tire BoBoiBoy out and get him to sleep. The actual time she spends running in the show is 5s. However, due to camera cuts I'm also going to assume 10s mid-end and 15s low-end. She couldn't have spent too much time running considering the fact that they were trying to put BoBoiBoy to sleep fast.
High-End[]
Distance = 1000km
Time = 5s / 60 / 60 = 1/720h
Speed = 1000km / 1/720h = 720000km/h (Mach 583)
Mid-End[]
Distance = 1000km
Time = 10s / 60 /60 = 1/360h
Speed = 1000km / 1/360h = 360000km/h (Mach 292)
Low-End[]
Distance = 1000km
Time = 15s / 60 / 60 = 1/240h
Speed = 1000km / 1/240h = 240000km/h (Mach 194)
Conclusion[]
All three values are varying degrees of Massively Hypersonic. This should be consistent with BoBoiBoy Thunderstorm creating actual cloud to ground lightning.
