An apparatus has a 5000 L tank supplying two pre-connected handlines at 600 L/min and 400 L/min. How many minutes of agent application are available?

Explanation:
The main idea is that how long the agent lasts depends on the tank volume divided by the total discharge rate. When two handlines are used at the same time, their flows add together, giving a combined flow of 600 L/min plus 400 L/min, which equals 1000 L/min. With a 5000 L tank, the available time is 5000 L divided by 1000 L/min, yielding 5 minutes of application.
