Firefighter Math · Question
Scenario 10: A structure fire requires two hose lines flowing at 150 GPM each. A third master stream device flows at 500 GPM. What is the total GPM required?
Calculate the flow from two hose lines: 2 * 150 GPM = 300 GPM. Then, add the master stream flow: 300 GPM + 500 GPM = 800 GPM. The correct answer is "800 GPM". T

Question: Scenario 10: A structure fire requires two hose lines flowing at 150 GPM each. A third master stream device flows at 500 GPM. What is the total GPM required?
Answer options:
- 650 GPM ✅ 800 GPM
- 700 GPM
- 950 GPM
Correct answer: 800 GPM
Explanation: Calculate the flow from two hose lines: 2 * 150 GPM = 300 GPM. Then, add the master stream flow: 300 GPM + 500 GPM = 800 GPM. The correct answer is "800 GPM". This capacity-fill scenario 10 reinforces the same competency for the firefighter-math bank and follows the certified explanation standard.
