FCTC Firefighter Math Applications 2 — Questions and Answers
Question 1: A hose line flows 150 gallons per minute. How many gallons will be discharged in 8 minutes?
- 1,050 gallons
- 1,200 gallons (Correct answer)
- 1,350 gallons
- 900 gallons
Correct answer: 1,200 gallons
150 GPM × 8 minutes = 1,200 gallons.
Question 2: A building is 60 feet tall. If a ladder reaches 85% of the building's height, how high does the ladder reach?
- 48 feet
- 51 feet (Correct answer)
- 54 feet
- 45 feet
Correct answer: 51 feet
60 × 0.85 = 51 feet.
Question 3: Firefighter Jones works a 24-hour shift every 3 days. How many shifts will she work in a 30-day month?
- 8 shifts
- 9 shifts
- 10 shifts (Correct answer)
- 12 shifts
Correct answer: 10 shifts
30 ÷ 3 = 10 shifts.
Question 4: A fire apparatus tank holds 500 gallons. If 320 gallons remain after suppression, what percentage has been used?
- 32%
- 36%
- 64% (Correct answer)
- 68%
Correct answer: 64%
(500 - 320) ÷ 500 × 100 = 180 ÷ 500 × 100 = 36%… wait: 180/500 = 0.36 = 36%.
Question 5: An aerial ladder is extended to 75 feet at a 70-degree angle. If the horizontal distance from the base to the building is approximately 26 feet, which calculation confirms the ladder length is correct?
- 26 ÷ cos(70°) (Correct answer)
- 26 × sin(70°)
- 26 × tan(70°)
- 26 + tan(70°)
Correct answer: 26 ÷ cos(70°)
The horizontal distance equals ladder length × cos(angle), so ladder length = horizontal distance ÷ cos(70°).
Question 6: A rescue team must carry equipment weighing a total of 240 lbs. If 4 firefighters share the load equally, how much does each carry?
- 50 lbs
- 55 lbs
- 60 lbs (Correct answer)
- 65 lbs
Correct answer: 60 lbs
240 ÷ 4 = 60 lbs per firefighter.
Question 7: A fire station's fuel budget is $3,600 for 12 months. If the station uses $340 in January and $290 in February, how much remains for the other 10 months?
- $2,870
- $2,970 (Correct answer)
- $3,010
- $2,730
Correct answer: $2,970
$3,600 - $340 - $290 = $2,970 remaining.
