So kiddo, you know how we often use numbers in math to help us figure things out? Well, the r=t model is a way for us to use numbers to understand how one thing is related to another.
Now, when we talk about the r=t model, the "r" stands for the result we're trying to figure out, and the "t" stands for the time it takes to get that result. For example, let's say we want to figure out how many cookies we can make in an hour. The "r" in this case would be the number of cookies, and the "t" would be the time it takes (which we agreed on as an hour).
To use the r=t model, we need to figure out what the "rate" is. The rate tells us how much of the result we get in a certain amount of time. So in our cookie example, if we can make 20 cookies in an hour, the rate would be 20 cookies per hour.
Once we have the rate, we can use the r=t model to figure out other things. For example, if we want to know how many cookies we can make in 2 hours, we can just multiply our rate (20 cookies per hour) by the number of hours (2). That gives us an answer of 40 cookies.
So in short, the r=t model is a way for us to figure out how one thing is related to another by using numbers and a rate. It helps us predict how much of something we can get in a certain amount of time.
