Question

The time, t, required to empty a tank varies inversely as the rate, r, of
pumping. If a pump can empty a tank in 2.5 hours at a rate of 400 gallons per
minute, how long will it take to empty a tank at 500 gallons per minute?

Answer 1

Answer:

2 hours

Step-by-step explanation:

2.5 * 400 = 1000

1000 / 500 = 2
