  1. An officer earns $52,000 per year. After a 5% raise, what is the new annual salary?

    Answer: $54,600

    5% of $52,000 = $2,600; $52,000 + $2,600 = $54,600.

  2. A shift has 4 officers patrolling 32 square miles. If 1 officer calls in sick and the patrol area stays the same, how many square miles must each remaining officer cover?

    Answer: 10.67 square miles

    32 ÷ 3 = 10.67 square miles per officer.

  3. A report takes 20 minutes to write. An officer has 3 hours at the end of shift. How many complete reports can the officer finish?

    Answer: 9 reports

    3 hours = 180 minutes; 180 ÷ 20 = 9 reports.

  4. A precinct responded to 1,200 calls last month. This month, calls increased by 25%. How many calls were received this month?

    Answer: 1,500 calls

    25% of 1,200 = 300; 1,200 + 300 = 1,500 calls.

  5. An officer drove 250 miles in 5 hours. What was the average speed?

    Answer: 50 mph

    250 ÷ 5 = 50 mph.

  6. A jail holds 300 inmates. If 60 are released and 45 new inmates arrive, what is the new total?

    Answer: 285 inmates

    300 − 60 + 45 = 285 inmates.
