<u><em>Part 1) What is the slope for section "d" of Mrs. Washington's commute</em></u>
As the slope for section "d" of Mrs. Washington's commute can be computed by the following formula:
⇒
Therefore, the slope for section "d" of Mrs. Washington's commute
<em><u>Part 2) What does it mean that the slope is negative in context of the problem?</u></em>
- The slope is negative in context of the problem means the slope is moving downward from the left.
- In negative slop, the value of x gets increased, while the vale of y gets decreased while in case of positive slop, the value of both x and y get increased.
<em><u>Part 3) Why are the slopes different over different intervals?</u></em>
- Slopes are different at different intervals. The reason is that the distance covered in time taken for each part of the given journey are different.
- Also, the speed is different for each interval depending upon the time taken to cover the distance.
Distance-time equation is needed to compute the speed
Let distance be denoted as d, and time be denoted as t
- d =
- t =
t= 8 - 0 = 8
As
Hence, the speed in the part 1 would be
<u>Part 4) How long does it take Mrs. Washington to get home? How did you know this?</u>
- After carefully observing the graph, it sounds clear that Mrs. Washington takes 32 minutes to reach home.
- It can be easily figured out from the graph that it represents the total time taken throughput the complete journey.
