Lag time at 4000 km depends on the context, such as whether it's related to signal transmission, such as light or radio waves. For light, which travels at approximately 299,792 kilometers per second, the lag time would be about 13.33 milliseconds (ms). In the case of radio waves, which also travel at light speed in a vacuum, the lag time remains the same. However, if you're referring to other forms of communication or travel, the lag time may vary based on the medium and technology used.
