a tank contains 1700 gallons of diesel fuel. a fuel mixture containing a lubricity additive is pumped into the tank through two inlets. the mixture flowing in through the first inlet contains 0.28oz of additive per gallon, and is being pumped in at a rate of 25gal/min. meanwhile, the mixture being allowed in by the second inlet at a rate of 10gal/min contains 14.9oz of additive per gallon. the mixture in the tank is continuously and thoroughly mixed and drained out at the rate of 20gal/min. if there should be 14oz of additive for every 120 gallons of diesel fuel, how long will it take to reach the right mixture? round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to three decimal places.
