C. UNIT RATES
Based on the graph, what is the unit rate of miles driven per day? SOLUTION: Find a point (x,y) on the graph to determine the unit rate. Using the point (2, 60), the ratio of y to x is 60 miles for 2 days. Since unit rate compares a quantity to one, convert 60 miles for 2 days to 30 miles per day.
