How fast is this?

[The_real_cal_howard]

"Imagine every city in the world, lined up. Multiply it by eighty. That distance...that's just the top"

This is describing a mountain. It's perfectly conical. A character runs up the mountain in a spiral fashion in about 10 seconds. How fast is the character?

 

[TheJ-ManRequiem]

Probably like quad, maybe quint digit mach I think.

Maybe if you can calc this size and multiply it by 80. https://www.youtube.com/watch?v=r_iNRGac_uM
