A suspect fled on foot at 6 km/h. An officer gave chase 5 minutes later at 10 km/h. How many minutes will it take the officer to catch the suspect?

Answer: 7.5 minutes

The suspect has a 0.5 km head start (6 km/h × 5/60 h); the officer closes the gap at 4 km/h, taking 0.125 hours = 7.5 minutes.

A fingerprint database contains 4,200 records. A new intake adds 15% more records. How many records are in the database after the intake?

Answer: 4,830

15% of 4,200 is 630, and adding this to 4,200 gives 4,830 records.

An officer submits 4 incident reports per day for 5 weekdays. The station target is 25 reports per week. By how many reports does the officer exceed the target?

Answer: 5

4 reports × 5 days = 20, but that falls short; 4 × 5 = 20 which is 5 below 25, so the officer meets exactly 20, missing by 5.

A budget of $9,600 is shared equally between 4 police units. How much does each unit receive?

Dividing $9,600 by 4 units gives $2,400 per unit.

A sequence of call numbers follows the pattern: 102, 106, 110, 114, ___. What is the next number?

Answer: 118

Each number increases by 4, so 114 + 4 = 118.

An officer earns $1,250 per week. After a 4% pay rise, what is the new weekly wage?

Answer: $1,300

4% of $1,250 is $50, so the new wage is $1,250 + $50 = $1,300.
