4км-2км 580 м

To subtract 2 kilometers and 580 meters from 4 kilometers, we need to first convert everything to the same unit.

1 kilometer is equal to 1000 meters.

So, 4 kilometers can be converted to meters as: 4 km * 1000 m/km = 4000 meters

Now we can subtract 2 kilometers and 580 meters from 4 kilometers:

4000 meters - (2 km * 1000 m/km + 580 m) = 4000 meters - (2000 meters + 580 meters) = 4000 meters - 2580 meters = 1420 meters

Therefore, 4 kilometers - 2 kilometers 580 meters equals 1420 meters.
