Okay, so this problem is talking about a jogger, and it gives us this graph right here, and it says that we need to explain it, but it already did like this first three sections.
00:13
Like where i did the dotted lines, those are going to indicate changes of what happened.
00:17
So like it says that this first one, she runs at a slow -biddy constant rate, right? because it's a straight line.
00:22
But then this next piece gets steeper, right, it's curved up.
00:26
That means she increased her pace, right? and it gave us that.
00:29
And then this next piece, she is a flat line.
00:32
Notice how like the distance is the same that whole time.
00:36
So maybe she stopped and ate a granola bar or something or other or ran into a friend and started chatting, right? her distance didn't change, therefore her rate is zero.
00:45
But then starting at this 20 minute, that's what we need to start explaining...
