    Answer:

      1.2 hours

    Step-by-step explanation:

    A fills 1/2 tank per hour; B fills 1/3 tank per hour, so together they fill …

      1/2 +1/3 = 3/6 +2/6 = 5/6 . . . . tank per hour

    The reciprocal of this rate give the rate in the units we want:

      6/5 hours per tank.

    __

    At that rate, it will take 6/5 = 1.2 hours to fill the tank.
