No answer is possible unless we ignore the real world.

In the real world, = => the skydiver jumps out of an airplane traveling with a horizontal velocity of 844 miles per hour, and is instantly torn to shreds as soon as she hits the supersonic air-stream, and = => we don't have enough information to solve the problem with air resistance, but the airplane can't fly without it.

Knowing all of this, we'll just accept the data as given, and ignore air resistance.

Gravity creates only vertical forces, and it has no effect on horizontal velocity. So Ms. Skydiver keeps plowing ahead at 377.3 m/s forever, or at least as long as we remain interested.

Distance = (speed) x (time)

Distance = (377.3 m/s) x (5.8 sec)

Distance = (377.3 x 5.8) (m-sec/sec)

Distance = 2,188 meters
