Time vs. difficulty on treadmill workout

I've been told that in order for me to lose weight, I need to work out approx. 200 minutes a week.
I have a treadmill and wonder if it's better to work out 200 minutes walking a brisk pace (3.5mph) or do less time, perhaps 150 minutes or so, walking slower but steep incline?
I'm about 25 pounds overweight. I'm a 46 year old female.
