Answer:

C - 40

Explanation:

The unit rate in a graph is how much a unit increases with time. The unit here is Distance (mi) and the time here is Time (h). So to find the unit rate, you divide the y-value with its corresponding x-value (given it is a straight line, which it is in this case).

So for example, let's take the unit 80mi, its corresponding x-value is 2, so 80/2 = 40. Let's do the same for 160mi, its corresponding x-value is 4, so 160/4 = 40 and so on. The value will be the same for all x-y values in the graph.

Answer: 40 miles/hr

Explanation:

The unit rate is the slope of the line. The slope is the Rise/Run, so pick any two points and calculate. I'll pick (2,80) and (4,160).

Rise is (160-80) = 80

Run is (4-2) = 2

Rise/Run, or slope, is 80/2 or 40 (miles/hour)
