A dispatcher receives calls at a rate of 15 per hour during peak time and 5 per hour during off-peak time. If peak lasts 4 hours and off-peak lasts 8 hours, how many calls are received in total?
Answer: 100
(15 × 4) + (5 × 8) = 60 + 40 = 100 calls total.
A bar chart shows the following incident counts by type: assault 80, theft 120, vandalism 40, fraud 60. What percentage of total incidents does theft represent?

Total = 300; 120 ÷ 300 × 100 = 40%.
A suspect states they traveled 180 km to a destination. If the speed limit was 90 km/h the entire way, what is the minimum travel time?

A department's annual report shows a crime index of 85 in 2023 and 102 in 2024 (base year 2020 = 100). This indicates that crime in 2024 compared to the base year is:
Answer: 2% above the base year level
An index of 102 means crime is 2% above the base year level of 100.
An officer needs to distribute 84 pamphlets equally among 7 community groups. How many pamphlets does each group receive?

A crime hotspot map shows that 3 out of every 5 reported thefts occur in a single district. If 200 thefts occur city-wide, how many occur in that district?
