Which do you think it is or can eliminate?

anonymous · Answer

I am pretty sure it is not B..

anonymous · Answer

It does't look like it matches the scenario.

sleepyjess · Answer

Correct he doesn't stop in graph B.

sleepyjess · Answer

Can you identify what is wrong with A? Hint: he goes in the wrong direction at some point

anonymous · Answer

And Graph D doesn't seem right either because the line stops at 90 when I think it should stop at 100

sleepyjess · Answer

Yes

anonymous · Answer

Wait, I see that in graph A, it looks like he stops walking completely but the scenario doesn't say he stopped at the end. So it's C?

sleepyjess · Answer

Yes it is C. Even though it shows he walked toward the mall for approx 15 sec instead of 10 it is the best match
