The second rescue and firefighting vehicle must reach the midpoint of the farthest runway in how many minutes?

• A. 3 Minutes
• B. 4 Minutes
• C. 4 1/2 Minutes
• D. 5 Minutes

Answer: (B)

In this scenario the key idea is setting response-time targets for the second ARFF unit to ensure redundancy and adequate coverage. Reaching the midpoint of the farthest runway is chosen because it provides a strategic point along the longest runway where the second vehicle can begin effective action even if the first unit is delayed, helping to control a developing incident quickly. The four-minute target reflects a balance between how far the vehicle must travel from its staging area and the typical speed and acceleration profile of rescue and firefighting equipment, including any delays due to road conditions or traffic. A three-minute target would require unrealistically high speeds or shorter distances, while four and a half minutes or five minutes would miss the standard window for ensuring timely second-vehicle coverage. Therefore, four minutes is the designated arrival time for the second unit at the farthest runway’s midpoint.
