WebA typical skydiver on a belly-to-earth position will reach terminal velocity at a speed of approximately 120 mph (193 km/h) and will freefall for about 30-60 seconds before opening the parachute. Once a parachute is open it reduces the speed down to at least 90% and skydivers glide to the ground at a relatively low speed of 12 mph.
