- 45 km (Correct answer)
- 30 km
- 60 km
- 50 km
Correct answer: 45 km
45 minutes is 0.75 hours; 60 km/h × 0.75 = 45 km.

- 30% (Correct answer)
- 25%
- 35%

120 divided by 400 multiplied by 100 equals 30%.
Question 3: If an officer earns $52,000 annually and receives a 5% raise, what is the new annual salary?
- $54,600 (Correct answer)
- $53,000
- $55,200

Question 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:
- Seasonal variation peaking mid-year (Correct answer)
