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.
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.
