You walk from home due east to school to get a book, and then you walk back west to visit a friend. The figure shows your distance D, in yards, east of home as a function of the time t, in minutes, since you left home. (d) Compute the average rate of change in D over the interval from t = 0 to t = 3. yd/min Compute the average rate of change in D over the interval from t = 3 to t = 6. yards per minute Compute the average rate of change in D over the interval from t = 6 to t = 9. yards per minute (e) What do your answers to part (d) tell you about how fast you are walking to school? (Select all that apply.) How is this related to the shape of the graph over the interval from t = 0 to t = 9? (f) At what time are you walking back west the fastest? You are walking back west the fastest at about minutes.
Note: this is part 2 of this question I asked earlier today.
You walk from home due east to school to get a book, and then you walk back west to visit a friend. The figure shows your distance D, in yards, east of home as a function of the time t, in minutes, since you left home.
(d) Compute the average rate of change in D over the interval from t = 0 to t = 3. yd/min
Compute the average rate of change in D over the interval from t = 3 to t = 6. yards per minute
Compute the average rate of change in D over the interval from t = 6 to t = 9. yards per minute
(e) What do your answers to part (d) tell you about how fast you are walking to school? (Select all that apply.)
How is this related to the shape of the graph over the interval from t = 0 to t = 9?
(f) At what time are you walking back west the fastest?
You are walking back west the fastest at about minutes.
d) To compute the average rate of change in D:
Consider the formula, Average rate of change=.
