Okay, so this is my first time organizing a challenge, I named it as SteemYourBrain Challenge.
The type of challenges appearing in the series are targeted to mind twist fellow steemians :)
Enjoy~
SteemYourBrain #1
You are running on a 1km track, you can run as slow as you like on the first 500m with v1.
At the moment you passed the 500m point, suddenly you decided to increase your average speed to finish the whole 1km track to 2v1.
Now the question is, how fast should you run now (v2):)?
Hint #1: For anyone getting weird answers, is this a mathematically possible method? How about physically?^^
The first one who came up with the correct answer will be awarded for 2 SBD!
However the first one who can explain the whole question/answer/the tricky part can get 3 SBD!
