Answer:
Sofia is correct.
Step-by-step explanation:
Mark's statement depends on the starting point. He can be correct if they started at the 0 mile, but in this case we don't know where they started. They could had started at the 12 mile and their current position after the walking would be 16 miles.
On the other hand, Sofia's statement doesn't depend on where they started. She refers to how much they walked, not to where they are after the walking. Since they stopped after 4 non-stopping miles, their displacement was exactly 4 miles. So Sofia is correct.
So 25.6 + 16.2 + 25.6 + 36.5 + 16.2 + 37.8 = 1961.48
I would say the second statement would best describe her work, because it is giving the most detail out of those statements.
Hope this helps!
