Alright, so we know that from t = 0 to t = 6 she is moving AWAY from her office

johnweldon1993 · Answer

From t = 6 to t = 10   she is not getting any closer to her office...so still not counting that

johnweldon1993 · Answer

Now from t = 10 to t = 12 she is moving towards it

and again from t = 12 to t = 16 she is moving toward it

mathstudent55 · Answer

When you see a positive slope, as shown below, as time increases, her distance to the office also increases. That means a positive slope means she is moving farther away from the office.

From 16 to 22...she is not moving...and then from 22 to 26...she is moving towards it

So what do we have

From 10 to 16 she is moving towards it...and again from 22 to 26 she is moving toward it

So how many minutes is that?

mathstudent55 · Answer

Below you see a piece of the graph with zero slope. As time passes, her distance to the office remains the same. That means she is stopped (or she is moving in a circle around the office), but she is definitely not getting closer to the office. That means a zero slope shows no movement getting closer to the office.

mathstudent55 · Answer

The second part of zero slope shows the same as the first one. She is not getting closer to the office.

LOL sorry is so funny c;

johnweldon1993 · Answer

Well from 10 to 16 is 6 minutes...then again from 22 to 26 would be another 4 minutes....so that makes, in total, a ______ minute journey?

mathstudent55 · Answer

From the graph, you can see that she got closer to the office in the intervals 10 minutes to 12 minutes, 12 minutes to 16 minutes, and 22 minutes to 26 minutes. How long are those three intervals combined?
