Answer 2

So If her distance to the office is growing, then she's moving further away from her office, and vice versa. So if you're looking for the duration of time that she spent moving towards her office, you'd simply look down on the x axis and count how many minutes that the line is going down, as during that time she is reducing her distance to her office. To me it looks like that would be between 8 and 16 minutes, as the distance is steadily decreasing, and again from 22 to 26 minutes,

Answer 3

~10 minutes

Answer 4

I thought 25 how you get that

Answer 5

@xVxNICKxVx What Would it Be

Answer 6

xVxNICKxVx has the right idea. But it's 10 to 16, and then 22 to 26 (see attached)

Answer 7

Yep, they're right! I knew I couldn't trust my eyes. All you need to do is add up those minutes and you've got your answer.

Answer 8

Something really important here to see is that the x axis, the one across the bottom, is not in a scale where a line equals one minute. As you can see, there is one bar between 0 and 4, which would mean that the distance between each vertical line is a period of two minutes. With this information, you can look at @jim_thompson5910 's great visualization and see how many sections of those lines you have. For the first red box, where she's getting closer to her office, there are three vertical columns, where each column is a period of two minutes. Same thing goes for the second box, but here the vertical lines intersect the x axis in between your time marks, so you need the information I mentioned at the start if you want to know from exactly what minutes she was getting closer to the office. There are two vertical columns in that box and each of those columns are two minutes. In total then, you have three * 2 minutes + 2 * two minutes which will give you the cumulative time she spent moving towards the office.
