Answer:
Micky had the lowest unit rate of 0.3
Step-by-step explanation:
For Jason, the distance travelled is given by:
[tex]d = \frac{1}{2}m[/tex]
The unit rate is the slope , which is ½ or 0.5
For Susan, she travels 3 miles is 5 minutes. Her unit rate is
[tex] \frac{3}{5} [/tex]
Or 0.6
We can determine, Micky's unit rate from the graph. Using (20,6) and (40,12) on the graph, we determine the unit rate using,
[tex]m = \frac{ y_2-y_1}{ x_2-x_1} [/tex]
[tex] \frac{12 - 6}{40 - 20} = \frac{6}{20} = 0.3[/tex]
Therefore Micky had the lowest unit rate
