45 miles per second is about 1,000 times as fast as a Skydiver (headfirst)
In other words, the speed of a Skydiver (headfirst) is 0.001 times that amount.
(Head-to-Earth orientation or standing, average conditions, terminal velocity)
A head-to-Earth or standing-oriented skydiver's terminal velocity assuming average conditions is about 0.045 miles per second. In a typical jump from 3,900 m (13,000 ft), a diver in this orientation will be in freefall for 46 seconds.
