Answer:
meters
Step-by-step explanation:
Let's take climbing down as "negative" and climbing up as "positive". Now, we can simply use the numbers and signs to find the change in elevation.
meters down means ![-2\frac{1}{2}](https://tex.z-dn.net/?f=-2%5Cfrac%7B1%7D%7B2%7D)
meters up means ![+6\frac{3}{4}](https://tex.z-dn.net/?f=%2B6%5Cfrac%7B3%7D%7B4%7D)
So, now we have: ![-2\frac{1}{2}+6\frac{3}{4}\\=-\frac{5}{2}+\frac{27}{4}\\=\frac{-5(2)+27}{4}\\=\frac{-10+27}{4}\\=\frac{17}{4}=4\frac{1}{4}](https://tex.z-dn.net/?f=-2%5Cfrac%7B1%7D%7B2%7D%2B6%5Cfrac%7B3%7D%7B4%7D%5C%5C%3D-%5Cfrac%7B5%7D%7B2%7D%2B%5Cfrac%7B27%7D%7B4%7D%5C%5C%3D%5Cfrac%7B-5%282%29%2B27%7D%7B4%7D%5C%5C%3D%5Cfrac%7B-10%2B27%7D%7B4%7D%5C%5C%3D%5Cfrac%7B17%7D%7B4%7D%3D4%5Cfrac%7B1%7D%7B4%7D)
<u>Eric's elevation changed
meters above. So after the 2 moves, he is up by

Don't you mean **Rodrigo? ; sorry if i sound mean saying that as if I'm correcting you in a bad manner.
Its A = If you want to know how I did it subtract 62-22 then what ever you get multiply it by 4 then Carry on from their
