We can see this problem is not linear, exponential, or quadratic. When we graph this situation we get a graph that looks like it might be exponential decay but there is another copy of the graph in quadrant 3. This makes it not exponential. We can see that if I multiply the rate and the time the distance is always 5000 so the equation is 5000/r=t. Anytime we divide by a variable (r) we get an inverse relationship. Inverse relationships are the opposite of linear equations that go through (0,0).
