  1. Over 5 days, a station received 32, 45, 28, 51, and 44 calls. What was the average number of daily calls?

    Answer: 40

    (32 + 45 + 28 + 51 + 44) ÷ 5 = 200 ÷ 5 = 40 calls per day.

  2. The ratio of sworn deputies to civilian staff at a station is 3:1. If there are 24 civilian staff members, how many sworn deputies are there?

    Answer: 72

    With a 3:1 ratio and 24 civilian staff, sworn deputies = 3 × 24 = 72.

  3. A suspect fled on foot and was captured after traveling 1.2 miles in 12 minutes. What was the suspect's average speed in miles per hour?

    Answer: 6 mph

    1.2 miles ÷ (12/60) hours = 1.2 ÷ 0.2 = 6 mph.

  4. A department budget was $2,400,000 last year and increased by 15% this year. What is this year's budget?

    Answer: $2,760,000

    $2,400,000 × 1.15 = $2,760,000 for this year's budget.

  5. A deputy's shift starts at 10:45 PM and lasts 8 hours and 30 minutes. What time does the shift end?

    Answer: 7:15 AM

    10:45 PM + 8 hours = 6:45 AM; 6:45 AM + 30 minutes = 7:15 AM.

  6. If 3 deputies can process 18 reports in 2 hours, how many reports can 5 deputies process in the same 2-hour period?

    Answer: 30

    Each deputy processes 6 reports in 2 hours; 5 × 6 = 30 reports total.

  7. A vehicle pursuit covers 12 miles at an average speed of 80 mph. Approximately how many minutes does the pursuit last?

    Answer: 9 minutes

    Time = 12 ÷ 80 = 0.15 hours; 0.15 × 60 = 9 minutes.
