Answer

Explanation:

Step1: Analyze starting points

At time = 0, Melissa's elevation is 8,342 feet and Corey's is 10,004 feet. Since they have different starting - point elevations, they could have started on different trails.

Step2: Analyze time durations

The table only gives discrete time - points. We cannot say for sure that Melissa hiked up the trail for a longer period of time just from this table.

Step3: Check for equal elevations

There is no time value between 0 and 90 minutes in the table where their elevations are the same.

Step4: Analyze descent

There is no indication in the table that Corey began his descent before Melissa.

Step5: Analyze Melissa's elevation change

From 0 to 60 minutes, Melissa's elevation increased from 8,342 feet to 11,239 feet, not decreased.

Answer:

Melissa and Corey started on different trails.
