  1. A fire scene requires 4 engine companies, each with 5 personnel. If 3 of the personnel are officers, how many non-officer personnel are on scene?

    Answer: 17

    Total = 4 × 5 = 20; non-officers = 20 − 3 = 17.

  2. A fire engine travels at 55 mph and must reach an incident 11 miles away. Approximately how many minutes will it take?

    Answer: 12 min

    11 ÷ 55 = 0.2 hours = 12 minutes.

  3. During training, a recruit correctly answers 84 of 120 questions. What is the recruit's score as a percentage?

    Answer: 70%

    84 ÷ 120 = 0.70 = 70%.

  4. A fire department's response time averages 5.4 minutes. New protocols aim to cut that time by 15%. What is the target response time?

    Answer: 4.59 min

    5.4 × 0.85 = 4.59 minutes.

  5. A hose weighs 1.8 pounds per foot. How much does 250 feet of hose weigh?

    Answer: 450 lbs

    1.8 × 250 = 450 pounds.

  6. A building's floor has an area of 6,400 square feet. If the building is square-shaped, what is the length of one side?

    Answer: 80 ft

    √6,400 = 80 feet per side.

  7. A station receives 5 supply deliveries per month, each containing 48 air cylinders. If each cylinder costs $85, what is the monthly supply cost for cylinders?

    Answer: $20,400

    5 × 48 × $85 = $20,400.
