Question

Assuming two hikers begin at a trail start, which scenarios must be true based on the table? Check all that apply.

Answer 1

Answer:

Correct Answers are:

A: Melissa and Corey started on different trails.

B: Melissa hike up the trail for a longer period of time than Corey

D: Corey began his descent before Melissa

Step-by-step explanation:

Melissa and Corey crossed paths between 60 and 90 minutes - False, because Melissa is increasing elevations as Corey is goes back down in elevations at the 60 minute mark.

As Melissa's time increased from 0 to 60 minutes, her elevation decreased - False, because her elevation only increases.

Answer 2

Answer:

Statements (1),(2),(3),(4) are correct and statement (5) is not correct.

Step-by-step explanation:

To check the correct statement we go through the statements one by one and validate it from the given chart.

1). At time t=0 Melissa started from 8342 feet height and Corey started from 10004 feet so the statement is true that both started on different trails.

2). Melissa hiked up for 90 minutes and reached at 12921 feet and Corey hiked for 60 minutes to reach at 12921 feet so Melissa hiked for a longer period than Carey. Therefore this statement is true.

3). Third statement that Melissa and Corey crossed paths between 60 and 90 minutes is right. We can see that at when Melissa was going up from 11239 feet to 12921 feet Corey started descending from 12921 feet so they crossed their paths.

4). Corey started descending from t=60 but Melissa didn't so the statement is true.

5). As Melissa's time increased from 0 to 60 minutes her elevation increased consistently from 8342 feet to 11239 feet so the statement that her elevation decreased is wrong.
