Sven, a wise man and a big time bet taker, was walking along when he came across Tommy. Sven wanted to make a quick buck so he said to Tommy, "I bet you $4,500 that you won't be able to stop accelerating in your car, after 10 seconds to get up to speed, on this circular track."

"Well, Sven, I'll take that bet. I just hope you don't cry too hard when I take your money."

So Tommy got his brand new red Porsche up to 90 mph and put it on cruise control. After four laps, he came up to Sven and paid him the $4,500. Why?


What shape was the track?

What Next?

But couldn't Tommy have braked his car, and then it would stop, meaning it wouldn't accelerate?

Oh, and how do you hand someone $4,500 instantly?

Using CC would automatically mean the car would slow or reduce its speed, never reaching the time limit of ten seconds.

Better than I could do, good teaser
