Answer: I'm gonna answer the last one
Explanation:
First lets add up Rosalva
1.5+0.69+1.04+2.1=5.33
Next lets do Jake
1,450+1,590+1204+1,977=6,221
We have two different measurements, we want them to be the same. We are gonna change Rosalva. One kilometer equals 1,000 meters. If u use the g o o g l e calculator it says that 5.33 kilometers equals 5330 meters. since u need to show work just multiple 5.33 by 1,000.
Last we need to find the difference soooooooo 6,221-5330=891 meter difference :)
