Answer

Brief Explanations:

  1. At time 0, their starting elevations are different, but this doesn't mean they are on different trails as they could start at different points on the same trail.
  2. The table doesn't give information about who hiked for a longer time; it just gives elevation - time data.
  3. At 60 minutes, Melissa's elevation is 11,239 feet and Corey's is 12,921 feet. At 90 minutes, Melissa's elevation is 12,921 feet and Corey's is 11,075 feet. So they must have crossed paths between 60 and 90 minutes.
  4. There is no indication of when they started descending from the table.
  5. As Melissa's time increased from 0 to 60 minutes, her elevation increased from 8,342 feet to 11,239 feet, not decreased.

Answer:

Melissa and Corey crossed paths between 60 and 90 minutes.
