Answer

Answer:

  • Melissa and Corey started on different trails.
  • Melissa hiked up the trail for a longer period of time than Corey.
  • Melissa and Corey crossed paths between 60 and 90 minutes.

Explanation:

Step1: Check starting elevations

At time = 0, Melissa's elevation is 8342 feet and Corey's is 10004 feet, so they started on different trails.

Step2: Check hiking - time

Melissa's data goes to 120 minutes and Corey's to 90 minutes, so Melissa hiked longer.

Step3: Check for path - crossing

At 60 minutes Melissa's elevation is 11239 feet and Corey's is 12921 feet. At 90 minutes Melissa's elevation is 12921 feet and Corey's is 11075 feet. So they crossed paths between 60 - 90 minutes.

Step4: Analyze descent

Corey's elevation starts decreasing at 90 minutes and Melissa's remains the same until at least 120 minutes, so Corey began his descent before Melissa is false.

Step5: Analyze Melissa's elevation change

As Melissa's time increased from 0 to 60 minutes, her elevation increased from 8342 to 11239 feet, so "As Melissa’s time increased from 0 to 60 minutes, her elevation decreased" is false.
