I need help please I will mark you brainiest

A: 1,200 meters

B: 350 meters

C: 2.55 kilometers

Step-by-step explanation:

A: 1 kilometer = 1000 meters so in order to to find how many meters Abbas walked, we need to take 1.2 * 1000 to get 1,200 meters.

B: For Zoey we are going to do the same thing. Take 0.85 kilometers * 1000 to get 850 meters. Now we subtract the number of meters Abbas walked to how many Zoey walked. 1,200- 850 to get 350 more meters, therefore Abbas walked 350 meters more than Zoey.

C: Now instead of converting kilometer to meters, we are converting meters to kilometers which means we need to divide by 1000. Marcelo walked 50 meters so we take 50 meters/1000 to get 0.5 kilometers. All that is left to do is add all the kilometers together to get

0.5 + 0.85 + 1.2 = 2.55 kilometers

Hope this helps!
