Oh, the next couple questions, they're all gonna be based on the graph you see in your book. And while I cannot draw that graph, precisely, I did want to draw a loose sketch to kind of be able to refer to it. So, um, we're starting with the question of what was her heart rate at the beginning before the beginning of the workout. So what was her heart rate at the beginning? And again, this graph is showing us the heart rate. So right here, that's the beginning of the workout. It's before. Well, I should say, this is the beginning. This is before the beginning. And since it's measuring her heart rate and it's flat at 60 we know her heart rate prior to starting working out is 60 beats per minute for be were asked, How long did it take her to reach her training zone? So this is where training zone starts. So we need to measure this length of time along our X axis. So if you look, of course, this is zero. And then the change happens when we hit 10 minutes. So a 10 minutes she began training
