4км-2км 580 м

To subtract 2 kilometers and 580 meters from 4 kilometers, we must first convert all measurements to the same unit, either kilometers or meters.

Converting 4 kilometers to meters: 4 kilometers = 4,000 meters

Now, we can subtract 2 kilometers and 580 meters from 4,000 meters: 4,000 meters - 2,000 meters - 580 meters = 1,420 meters

Therefore, 4 kilometers - 2 kilometers 580 meters is equal to 1 kilometer 420 meters.
