Where did u get 1.47?

[@Trump_Gaming]

It's just a shortcut to convert miles per hour to feet per second. 5280 ft / 3600 s = 1.47. But he did not use this conversion in the second part of the SSD equation, which he should have.

bro, thank you so much!

[@AE-is4rj]

shouldn't we convert the MPH to ft/sec for the designed speed?

[@Trump_Gaming]

Yes. He did that wrong. I know this is an old comment but yes.
