That would depend upon her average speed during the 110 seconds of falling. If she had been in free fall with no air resistance, she would have reached a velocity of g t = 3500 ft/s in 110 seconds. Since her actual velocity when the parachute starts to open in much less, she must have been at or near the terminal velocity of 30 ft/s (44 mph) during most of the free fall.
So a good approximation to the answer is 110 s x 30 ft/s = 3300 feet
So a good approximation to the answer is 110 s x 30 ft/s = 3300 feet

Actually 30 ft/s is 20.5 mph. That seems like a very slow limiting velocity for someone falling out of an airplane.
I still believe they expect you to answer 3300 feet.
