With a water tank capacity of 14,250 gallons, how many hours will it take to fill it using only pumps B and C?

To determine how long it will take to fill a 14,250-gallon water tank using only pumps B and C, we first need to know the flow rates of each pump. If we assume the combined flow rate of both pumps is known from prior calculations or given data, we can then use this rate to find the filling time.

Let’s say pump B has a flow rate of 'x' gallons per hour and pump C has a flow rate of 'y' gallons per hour. The combined flow rate when both pumps are used together would be (x + y) gallons per hour. To find the time needed to fill the tank, we apply the formula:

Time = Volume / Flow Rate

Here, the volume is the tank's capacity, which is 14,250 gallons. Thus, we can express the time it takes to fill the tank as:

Time = 14,250 gallons / (x + y)

If the calculation results in 19 hours, that suggests that the combined flow rate of pumps B and C is such that when you plug it into the equation, you achieve the correct volume of the tank being filled in the time specified. Therefore, if you know that the flow rates of pumps B and C add
