9. Use Fig. 27.18 to measure and calculate: a. the distance from points A to B b. the distance from points B to C c. the average velocity, if the journey from point A to point C took 5 minutes
B
A :Fig. 27.18 10. A jogger’s run is shown in the following graph:
500 1000 1500 2000 2500 3000
A 0 0 Time (s) :Fig. 27.19
a. How do you think the jogger measured their distance and time? b. Calculate the jogger’s average speed between points A and B. c. Calculate the jogger’s average speed between points C and D. d. Why do you think the average speed is different for the first and last sections of the run? e. Explain why the line between points B and C is horizontal.
