Frank can type a report in 4 hours and James takes 6 hours. How long will it take the two of them typing together?

  • math -

    Add the two hours together.

  • correction - math -

    Brooke's answer makes no sense

    Frank's rate = 1/4
    James rate = 1/6
    combined rate = 1/4 + 1/6 = 5/12

    time at combined rate = 1/(5/12)
    = 12/5
    = 2.4 hours

  • math -

    290*484-59385\6853]3763]= 1480264095740
