  1. A patrol officer drives 24 miles in 36 minutes. What is the officer's average speed in miles per hour?

    Answer: 40 mph

    24 miles ÷ 36 minutes × 60 minutes/hour = 40 mph.

  2. A supply room has 144 flashlights distributed equally among 12 officers. If 3 officers return their flashlights, how many flashlights are back in storage?

    Answer: 36

    144 ÷ 12 = 12 flashlights per officer; 3 × 12 = 36 returned.

  3. An officer's shift pays $22.50 per hour. How much does the officer earn for a 8.5-hour shift?

    Answer: $191.25

  4. A rectangular checkpoint zone measures 45 feet by 30 feet. What is the perimeter of the zone?

    Answer: 150 feet

    Perimeter = 2(45 + 30) = 2(75) = 150 feet.

  5. If 5/8 of a 200-person crowd is cleared from an area, how many people remain?

    Answer: 75

    5/8 × 200 = 125 cleared; 200 − 125 = 75 remain.

    Answer: 19

    (18 + 23 + 15 + 20) ÷ 4 = 76 ÷ 4 = 19.
