Each end of the MK-124 will burn for about _________ seconds.

The MK-124 is a signaling device commonly used in maritime operations, particularly by the Coast Guard and other service members. It consists of a flare that can emit visible light and produce smoke, making it useful for signaling distress or marking locations during search and rescue missions.

The correct duration of the burn time for each end of the MK-124 is approximately 20 seconds. This timing is crucial because it allows personnel to coordinate their actions effectively, whether it's signaling for help or marking a position. Knowing that each end burns for this specific duration helps boat crew members manage their expectations during emergency situations, ensuring they can be seen or located as intended.

It's important to remember this burn time for effective communication during high-stress scenarios. If boat crew members misjudge the timing, they could miss the opportunity for rescue or provide insufficient signal, which highlights the significance of understanding the device thoroughly.
