Question

Alyssa started hiking at an elevation of 1500ft. After 2 hours, she was at 1200ft. Which integer desceibes her change in elevation?

A) 300
B) -300
C) 285
D) not enough info.

Answer 1

-300.

Explanation:

First, you'd have to subtract 1500 from 1200. This gives you 300, but since she is descending rather than ascending, the number is negative rather than positive.

Answer 2

My best guess is -300

Explanation:

Because she(?) moved lower while she hiking. So the number will be negative ( - ). And we can calculate the difference: 1500-1200=300
