Question

A penguin starts at 15 meters above sea level and ends at 7 meters below sea level. What is the change in elevation?

Answer 1

22 meters

Explanation:

If the penguin goes from 15 meters above sea level to sea level (0 meters), they traveled 15 meters in elevation.

Then they traveled another 7 meters when going 7 meters below sea level.

15 + 7 = 22

Hope this helps :)
