Bezzdna [24]

Answer:

24,800 meters

Step-by-step explanation:

We basically have to convert km to m, or kilometers to meters. For this we need the conversion factor:

1000 meters = 1 kilometers

So change from kilometers to meters, we simply need to multiply by 1000. Thus, we would have:

24.8 km * 1000 = 24,800 meters

Thus,

24.8 km = 24,800 m
