Question 1

A town's crime rate decreased from 480 incidents per year to 360 incidents per year. What is the percentage decrease?

Accepted Answer

25%

Answer

Decrease = 480 − 360 = 120; percentage = 120 ÷ 480 × 100 = 25%.

Question 2

An officer issues citations at a ratio of 3 speeding tickets for every 2 parking violations. If she issued 25 citations total, how many were speeding tickets?

Accepted Answer

15

Answer

Ratio 3:2 means 3/5 of citations are speeding; 3/5 × 25 = 15.

Question 3

A patrol car gets 22 miles per gallon. If gas costs $3.50 per gallon, what is the fuel cost to drive 110 miles?

Accepted Answer

$17.50

Answer

Gallons needed = 110 ÷ 22 = 5; cost = 5 × $3.50 = $17.50.

Question 4

A suspect ran for 2.5 minutes before being caught. If the officer ran at 12 mph and the suspect ran at 9 mph, how far (in feet) did the officer cover? (1 mile = 5,280 feet)

Accepted Answer

2,640 ft

Answer

12 mph × (2.5/60) hr = 0.5 miles; 0.5 × 5,280 = 2,640 feet.

Question 5

Shift A arrests 18 people, Shift B arrests 12, and Shift C arrests 15. What percentage of total arrests came from Shift B?

Accepted Answer
