If a tank is emptied in 5 minutes by a pump that is pumping at a rate of 300 gallons per minute, how long will it take to empty the tank with a pump that will pump at a rate of 500 gallons per minute?

To answer this question, we need to use the concept of rates.
The first pump empties the tank in 5 minutes at a rate of 300 gallons per minute. We can calculate the total volume of the tank by multiplying the rate of the first pump by the time it takes:
Total volume = Rate * Time = 300 gallons/minute * 5 minutes = 1500 gallons
Now, we want to find out how long it will take to empty the same tank with a pump that pumps at a rate of 500 gallons per minute.
Using the formula:
Time = Total volume / Rate
We can substitute the values into this formula:
Time = 1500 gallons / 500 gallons per minute = 3 minutes
Therefore, it will take 3 minutes to empty the tank with a pump that pumps at a rate of 500 gallons per minute.
300gal./min * 5min. = 1500 gal.
500T = 1500.
T =
