0-25 swimmers require how many lifeguards?

• A. 2 lifeguards
• B. 4 lifeguards
• C. 3 lifeguards
• D. 1 lifeguard

Answer: (C)

The main idea is that lifeguard staffing is tied to how many swimmers a guard can effectively watch. A single lifeguard can typically monitor up to 25 swimmers, so up to 25 people in the water is covered by one guard. When the number of swimmers increases, you add guards to maintain the same level of vigilance—for example, more guards are needed as groups grow beyond 25. This keeps scanning and response times practical and reliable. Of course, some settings with unusual layouts or hazards might adjust the ratio, but the standard guideline for 0–25 swimmers is one lifeguard.
