![]() So, if we go plus one rotations, we're going to go down 2 1/2 meters. So she only needs one more rotation to cover this next 2 1/2 meters. We also know that in every one rotation, she gets 2 1/2 meters closer. ![]() Take to get to the tree? Well, we know that after 12 rotations, she's only 2 1/2 metersĪway from the tree. And last but not least, how many rotations did it So if we divide both of theseīy four, what would we get? Well, that's the same thing asĢ 1/2 meters in one rotation. Saw that with four rotations, she's traveling 10 meters, so we could say 10 meters in four rotations. How far does Kaya travel with each rotation? All right, well, we already So 32.5 meters is how far the tree was to begin with when Kaya If we take away four rotations, to get us back to zero rotations, then we will go 10 meters further. And if we're going at a constant rate, well, then we would add 10 meters. So if we're going back by four, so we're subtractingįour from the rotations. If we want to figure out howįar the tree was to begin with, we have to go back to zero rotations. We see that if we increaseīy another four rotations, so let's say plus four rotations, we see that we have gottenġ0 meters closer to the tree, or our distance to the tree How far away was the tree to begin with? So the way that I would think about it is, after four rotations, we'reĢ2 1/2 meters from the tree. Take to get to the tree? So like always, pause this video, and see if you can answer these questions on your own before we do it together. With each rotation? How many rotations did it Was the tree to begin with? How far does Kaya travel So she's getting closer and closer the more rotations that her tire has had. When it rotated 12 times, then she's only 2 1/2 meters to the tree. Then once she's rotated eight times, she's 12 1/2 meters from the tree. So once her tire rotated four times, she was 22 1/2 meters from the tree. The table below shows the relationship between her distance to the tree and how many times her front tire rotated. Kaya rode her bicycle toward a tree at a constant speed.
