Answer: A and D
Step-by-step explanation:
A: The flat, horizontal lines in the draph mean the distance has not changed. So the flat line at the bottom of Erin's graph means she has not moved from home the first 10 minutes.
B is false. Mack was moving during the first 10 minutes and stopped to rest during the second 10 minutes.
C is false. the amount of vertical change in the 2nd and 3rd intervals is not as much as the change in in the 1st interval
D: THe slopes of the 3rd intervals in both graphs are the same which means they both walked the same distance in the same time.
E. False. Both graphs end at the same height at the end of the 30 minutes shown in the graph.
