CPM Homework Help : PC Problem 9-89

Sketch two graphs, one to show Anne’s rate over time and one to show the distance she traveled over time.

Rate Over Time Graph:

First quadrant, x axis labeled time, minutes, scaled from 0 to 75, y axis labeled speed, mph, scaled from 0 to 75, continuous linear piecewise, starting at (0, comma 30), turning as follows: at (15, comma 30), at (15, comma 60), at (45, comma 60), at (45, comma 0), at (60, comma 0), at (60, comma 30), ending at (75, comma 30).

Distance Over Time Graph:

First quadrant, x axis labeled time, minutes, scaled from 0 to 75, y axis labeled distance, miles, scaled from 0 to 45, continuous linear piecewise, starting at (0, comma 0, turning as follows: at (15, comma 7.5), at (45, comma 37.5), at (60, comma 37.5), ending at (75, comma 45).
