Question 1: A vehicle traveling at 60 mph needs 4.5 seconds to stop. Approximately how many feet does it travel before stopping? (1 mph ≈ 1.47 ft/s)
- 356 feet
- 382 feet
- 396 feet (Correct answer)
- 420 feet
Correct answer: 396 feet
60 × 1.47 = 88.2 ft/s × 4.5 s ≈ 396.9 ≈ 396 feet.
Question 2: If a patrol sergeant oversees 9 officers and each officer files 4 reports per shift, how many total reports are filed per shift?

- 6 hours
- 7 hours
- 8 hours (Correct answer)
- 9 hours
Correct answer: 8 hours
0.12 ÷ 0.015 = 8 hours.
Question 4: A department stores 3 boxes of evidence per shelf, and has 14 shelves. How many evidence boxes can be stored in total?
- 38
- 40
- 42 (Correct answer)
- 45

Correct answer: 2:35 PM
1435 military = 14:35 = 2:35 PM standard time.
Question 6: If an officer walks a beat of 2.4 miles in 48 minutes, what is the walking pace in miles per hour?
- 2.5 mph
- 3.0 mph (Correct answer)
- 3.5 mph
- 4.0 mph
Correct answer: 3.0 mph
2.4 miles ÷ 0.8 hours (48 min) = 3.0 mph.
