MATH RADICALS

Hi, my name is Blair Kirkland and I am in a grade nine math student in St.John's Newfoundland. One of my favorite sports is downhill skiing. However the closest hill to me is about a two hour drive east to Clarenville. There is nothing quite like flying down over the hills, as fast as possible. I also have a twin brother named Ian who is almost as good a skier as I am. We have both been skiing for about four years.
Problem: Ian is at the top of the hill that is 1000 meters high and I am on the top of a hill that is 1200 meters high. Ian skies down the hill at 50 kilometers/hr and I ski down at 60 kilometers/hr. If we both start skiing at the same time who will reach the bottom first?
