    Answer:Maria rate = 1/13 job/hr

    —–

    Felipe rate = 1/16 job/hr

    —-

    Together rate = 1/x job/h

    Step-by-step explanation: rate + rate = Together rate

    1/13 + 1/16 = 1/x

    —-

    16x + 13x = 13*16

    ——

    29x = 13*16

    x = 7.17 hrs = 7 hr 10 min 12 seconds (time to do the job together)
