Answers
Given : The graph representing Jason's speed on a recent trip and options A) between 0 and 5 minutes B) between 5 and 10 minutes C) between 10 and 20 minutes D) between 20 and 25 minutes
To find : time period for which rate of change negative?
Solution:
See attached graph
rate of change
between 0 and 5 minutes
= (40 - 0)/(5 - 0)
= 40/5
= 8
between 5 and 10 minutes
= (50 - 40)/(10 - 5)
= 10/5
= 2
between 10 and 20 minutes
= (50 - 50)/(20 - 10)
= 0/10
= 0
between 20 and 25 minutes
= (40 - 50)/(25 - 20)
= -10/5
= -2
rate of change negative
for time period between 20 and 25 minutes rate of change negative
