Terminal velocities of a human skydiver on Earth:

Belly-to-earth position: Terminal velocity will be reached at around 2.5 seconds. Speed will be around 200 kph or 120 mph.
Head-down position: Terminal velocity will be reached at around 6.5 seconds. Speed will be around 600 kph or 370 mph.

Speed of sound is 343 meters per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 knots).
