4км-2км 580м

To find the difference between 4 km and 2 km 580 m, we can convert both distances to the same unit, such as meters, and then subtract.

4 km = 4,000 m (1 km = 1,000 m)
2 km 580 m = 2,580 m

Now, we can subtract:

4,000 m - 2,580 m = 1,420 m

Therefore, the difference between 4 km and 2 km 580 m is 1,420 meters.
