Two pumps are filling large vats of liquid. One vat is empty, and the pump is filling it at a rate of 6 gallons per minute. The other vat already contains 28 gallons and is continuing to fill at a rate of 4 gallons per minute. When will the two vats have the same amount of liquid? (1 point)

1 answer

10 minutes.

After 10 minutes, the first vat will have 6 gallons * 10 minutes = 60 gallons of liquid.
After 10 minutes, the second vat will have 28 gallons + (4 gallons * 10 minutes) = 28 gallons + 40 gallons = 68 gallons of liquid.

Therefore, after 10 minutes, both vats will have the same amount of liquid.
