Her first rate was faster. The 10 minutes with a change in elevation of - 200ft.

In order to solve this you need to have the same minutes. In this problem, I just simply took the 10 minutes and the - 200ft and doubled it. Now both rates have 20 minutes. The first rate would have gone - 400ft in 20 minutes while the second rate was only - 300ft in 20 minutes. I hope this wasn't confusing, and I'm willing to explain more.
