By finding some points on the curve and then connecting them.
<h3>How to graph the rational function?</h3>
Here we have the rational function:
t = d/s
Where t represents time, d distance, and s speed.
We assume that d is a fixed value, then our variables are time and speed.
On the examples, you can see that the value of d is:
d = 616.5km, then we just need to graph the equation:
t = (616.5km)/s
To do so, you can evaluate the function in different values of s, like the points the problem asks to graph, and then connect all these points with a curve.
Doing that, you should get a graph like the one below:
