Question 1

An officer responds to a call that is 21 miles away. If the officer travels at an average speed of 56 mph, how many minutes will it take to arrive on scene?

Accepted Answer

22.5 minutes

Answer

To solve this, use the formula Time = Distance / Speed. Time = 21 miles / 56 mph = 0.375 hours. To convert hours to minutes, multiply by 60. So, 0.375 * 60 = 22.5 minutes.

Question 2

An officer works a shift from 21:00 (9:00 PM) on Tuesday to 05:30 (5:30 AM) on Wednesday. The officer took a 45-minute meal break. How many hours and minutes did the officer actually work?

Accepted Answer

7 hours, 45 minutes

Answer

First, calculate the total time elapsed. From 21:00 to midnight is 3 hours. From midnight to 05:30 is 5.5 hours. The total shift duration is 3 + 5.5 = 8.5 hours, or 8 hours and 30 minutes. Then, subtract the 45-minute break: 8 hours 30 minutes - 45 minutes = 7 hours and 45 minutes.

Question 3

A rectangular crime scene measures 60 feet in length and 35 feet in width. What is the total perimeter of the scene that must be secured with police tape?

Accepted Answer

190 feet

Answer

The formula for the perimeter of a rectangle is P = 2(length + width) or P = 2l + 2w. Using this formula: P = 2(60) + 2(35) = 120 + 70 = 190 feet. The answer '2,100 square feet' represents the area, not the perimeter.

Question 4

An officer is logging evidence from a narcotics seizure. The total weight of the confiscated substance is 2,450 grams. How much is this in kilograms?

Accepted Answer

2.45 kg

Answer

There are 1,000 grams in 1 kilogram. To convert grams to kilograms, you divide the number of grams by 1,000. So, 2,450 / 1,000 = 2.45 kilograms.

Question 5

During a burglary investigation, an officer inventories the stolen items: a television valued at $1,250, two laptops valued at $780 each, and jewelry with a total value of $2,150. What is the total value of the stolen property?

Accepted Answer

$4,960

Answer

First, calculate the total value of the laptops: 2 * $780 = $1,560. Then, add the value of all the items together: $1,250 (TV) + $1,560 (laptops) + $2,150 (jewelry) = $4,960.
