    Drawing stuff like this is always the best choice. Can you try?

    Yes, you can see that she needs to fall 20,000 ft and then fall 15 ft more. If it was a 15 ft above sea level then she would need to fall 15 ft less

    That's correct. Here's another one for practice. How much would it be if it she jumped from 20,000 ft above sea level and landed 1000 ft ABOVE sea level?
