  1. A radio battery lasts 12 hours. If an officer starts a shift at 7:00 AM with a fully charged battery, at what time will it need replacing?

    Answer: 7:00 PM

    7:00 AM + 12 hours = 7:00 PM.

  2. If 5 officers can clear a building in 30 minutes, how long would it take 10 officers to clear the same building (assuming equal work distribution)?

    Answer: 15 minutes

    Doubling the workforce halves the time: 30 ÷ 2 = 15 minutes.

  3. A suspect's description states the individual is between 5'9" and 6'1" tall. Which of the following heights is within that range?

    Answer: 70 inches

    5'9" = 69 inches and 6'1" = 73 inches; 70 inches falls within that range.

  4. A supply room has 15 boxes of gloves, each containing 24 pairs. After distributing 216 pairs, how many pairs remain?

    Answer: 144

    Total pairs = 15 × 24 = 360; remaining = 360 − 216 = 144 pairs.

  5. An officer works 5 days a week for 3 weeks, then has 2 days off before starting a new cycle. How many work days are completed in 4 full cycles?

    Answer: 60 days

    Each cycle = 15 work days; 4 cycles = 4 × 15 = 60 work days.

  6. A secured area is 150 feet long and 80 feet wide. What is its perimeter?

    Answer: 460 feet

    Perimeter = 2 × (150 + 80) = 2 × 230 = 460 feet.

  7. If a security checkpoint processes 24 vehicles per hour, how many vehicles will it process during a 6.5-hour shift?

    Answer: 156

    24 × 6.5 = 156 vehicles processed during the shift.
