Question 1

An officer responds to 8 calls during an 8-hour shift. The next shift she responds to 25% more calls. How many calls did she respond to on the second shift?

Accepted Answer

10

Answer

25% of 8 is 2, so 8 + 2 = 10 calls on the second shift.

Question 2

A patrol car travels 60 miles per hour. How far will it travel in 45 minutes?

Accepted Answer

45 miles

Answer

45 minutes is 3/4 of an hour, and 60 × 0.75 = 45 miles.

Question 3

A police precinct has 120 officers. If 15% are assigned to detective duties, how many officers are on patrol?

Accepted Answer

102

Answer

15% of 120 = 18 detectives; 120 − 18 = 102 patrol officers.

Question 4

An officer writes 4 parking tickets per hour. Her partner writes 6 per hour. Working together for 3 hours, how many tickets do they write in total?

Accepted Answer

30

Answer

Combined rate is 10 tickets/hour; 10 × 3 = 30 tickets total.

Question 5

Evidence collected at a scene weighs 3 pounds 8 ounces. A second item weighs 1 pound 12 ounces. What is the combined weight?

Accepted Answer

5 lbs 4 oz

Answer

8 oz + 12 oz = 20 oz = 1 lb 4 oz; 3 + 1 + 1 = 5 lbs and 4 oz remaining.
