  1. An officer collects 3 statements at one scene and 5 at another. If each statement takes 15 minutes, how many minutes total?

    Answer: 120 minutes

    (3 + 5) × 15 = 8 × 15 = 120 minutes.

  2. A radar gun records speeds of 60, 65, 70, and 65 mph. What is the average speed?

    Answer: 65 mph

    (60 + 65 + 70 + 65) ÷ 4 = 260 ÷ 4 = 65 mph.

  3. If a suspect fled at 30 mph for 2 hours, how many miles did they travel?

    Answer: 60 miles

    30 mph × 2 hours = 60 miles.

  4. A budget of $1,200 is split among 4 patrol units. If one unit gets $450, how much is left for the other three?

    Answer: $750

    1,200 - 450 = $750 remaining for three units.

  5. Convert 3/4 to a percentage.

    Answer: 75%

    3 ÷ 4 = 0.75 = 75%.

  6. An officer issues 6 tickets per hour. How many tickets in a 7-hour shift?

    Answer: 42

    6 × 7 = 42 tickets.

  7. If a report is 28 pages and an officer has completed 7 pages, what fraction remains?

    Answer: 3/4

    7 of 28 is done, so 21/28 = 3/4 remains.
