Question 1: An officer clocks a vehicle traveling 78 mph in a 55 mph zone. By how many mph is the driver exceeding the speed limit?
- 21 mph
- 22 mph
- 23 mph (Correct answer)
- 24 mph
Correct answer: 23 mph
Subtract the speed limit from the actual speed: 78 − 55 = 23 mph over the limit.
Question 2: A police station has 120 officers. If 15% are assigned to detective work, how many officers work as detectives?
- 12
- 15
- 18 (Correct answer)
- 20
Correct answer: 18
15% of 120 officers = 0.15 × 120 = 18 detectives.
Question 3: Evidence bags weigh 2.5 pounds each. If an officer must transport 16 bags, what is the total weight?
- 36 lbs
- 38 lbs
- 40 lbs (Correct answer)
- 42 lbs
Correct answer: 40 lbs
Total weight = 2.5 × 16 = 40 pounds.
Question 4: A report states that incidents increased from 200 last year to 250 this year. What is the percentage increase?
- 20%
- 25% (Correct answer)
- 30%
- 35%
Correct answer: 25%
Percentage increase = (250 − 200) / 200 × 100 = 50/200 × 100 = 25%.
Question 5: An officer has $180 in a petty cash fund and spends $47.50 on supplies. How much money remains?
- $122.50
- $132.50 (Correct answer)
- $133.50
- $142.50
Correct answer: $132.50
$180.00 − $47.50 = $132.50 remaining in the petty cash fund.
Question 6: A patrol car travels 18 miles to the north, then 24 miles to the east. What is the straight-line distance back to the starting point?
- 28 miles
- 30 miles (Correct answer)
- 32 miles
- 42 miles
Correct answer: 30 miles
Using the Pythagorean theorem: √(18² + 24²) = √(324 + 576) = √900 = 30 miles.
