The distress signal light emits about how many flashes per minute?

• A. 30 per minute
• B. 70 per minute
• C. 90 per minute
• D. 50 per minute

Answer: (D)

A distress signal light is designed to be clearly noticeable and quickly recognizable as a call for help, so its flashing pattern is standardized. The typical rate is about 50 flashes per minute, which works out to roughly one flash every 1.2 seconds. This steady, moderate tempo makes the signal easy for rescuers to spot and count from a distance or in challenging conditions. If the rate were much slower, around 30 per minute, the signal might blend into the background or take too long to notice; if it were faster, like 70 or 90 per minute, it could appear frantic or be harder to track consistently. For these reasons, about 50 flashes per minute is the standard.
