  1. A patrol car travels at 60 km/h for 45 minutes. How far does it travel?

    Answer: 45 km

    45 minutes is 0.75 hours; 60 km/h × 0.75 = 45 km.

  2. A table shows that 120 of 400 incidents last month involved domestic disputes. What percentage of incidents were domestic disputes?

    Answer: 30%

    120 divided by 400 multiplied by 100 equals 30%.

  3. If an officer earns $52,000 annually and receives a 5% raise, what is the new annual salary?

    Answer: $54,600

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

  4. A crime data chart shows incidents rising steadily from January to June, then falling from July to December. The best description of this trend is:

    Answer: Seasonal variation peaking mid-year

    A rise followed by a fall over the year describes a seasonal pattern with a mid-year peak.

  5. Four suspects each had different amounts of stolen goods valued at $200, $350, $150, and $500. What is the mean value of stolen goods?

    Answer: $300

    $200 + $350 + $150 + $500 = $1,200; $1,200 ÷ 4 = $300.

  6. A precinct clears 90 of 150 reported cases in a month. What is the case clearance rate?

    Answer: 60%

    90 divided by 150 multiplied by 100 equals 60%.
