Question 1

A patrol officer works a 10-hour shift and spends 35% of it on traffic stops. How many minutes does the officer spend on traffic stops?

Accepted Answer

210 minutes

Answer

10 hours × 60 minutes = 600 minutes; 600 × 0.35 = 210 minutes.

Question 2

A suspect fled on foot at 8 mph. An officer began pursuit 3 minutes later running at 12 mph. How many minutes will it take the officer to catch the suspect?

Accepted Answer

6 minutes

Answer

The suspect's head start = 8 × (3/60) = 0.4 miles; closing speed = 4 mph; time = 0.4/4 hours = 6 minutes.

Question 3

A police department seized $48,750 in drug money. After returning $6,250 in legitimate funds and splitting the remainder equally among 3 agencies, how much does each agency receive?

Accepted Answer

$14,750

Answer

$48,750 − $6,250 = $42,500 ÷ 3 ≈ $14,166.67, which rounds to $14,167, but exact split is $14,166.67; closest listed answer representing division is $14,167.

Question 4

An officer clocked a vehicle traveling 82 mph in a 55 mph zone. By what percentage did the driver exceed the speed limit (rounded to the nearest whole percent)?

Accepted Answer

49%

Answer

(82 − 55) / 55 × 100 = 27/55 × 100 ≈ 49%.

Question 5

A precinct has 240 officers. If 15% are detectives, 25% are patrol officers on day shift, and the rest are on other assignments, how many officers are on other assignments?

Accepted Answer

144

Answer

15% + 25% = 40%; 100% − 40% = 60%; 240 × 0.60 = 144 officers.
