describing a possible scenario for a table\nhiking elevation(feet)\nassuming two hikers begin at a trail - start, which scenarios must be true based on the table? check all that apply.\ntime (min) melissa corey\n0 8,342 10,004\n30 9,550 11,432\n60 11,239 12,921\n90 12,921 11,075\n120 12,921 10,004\nmelissa and corey started on different trails.\nmelissa hiked up the trail for a longer period of time than corey.\nmelissa and coreys elevations were same at some time between 60 and 90 minutes.\ncorey began his descent before melissa.\nas melissas time increased from 0 to 60 minutes her elevation decreased.
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.
