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.

My best guess is - 300

Step-by-step explanation:

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

-300.

Step-by-step 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.
