A pump can be adjusted to empty a 1000-liter pool at different rates. When operated at a rate of liters per minute, the pump takes minutes to empty the pool. Which equation below relates and correctly?
..xxxx is liters/min
1000=xxxx*time
or time= 1000/xxxx
To find the equation that relates the pump rate () and the time it takes to empty the pool (), we need to analyze the information given.
The question states that when the pump operates at a rate of liters per minute, it takes minutes to empty the pool.
From this information, we can infer that the amount of water the pump can empty in minutes is equal to the rate () multiplied by the time ():
Amount of water emptied = ×
Since the amount of water emptied should be equal to the volume of the pool (1000 liters), we can set up the equation:
× = 1000
Simplifying this equation gives us the correct answer:
= 1000/
