    Welcome to PF!

    Hi joanne! Welcome to PF! :smile:

    Hint: this is an algebra problem.

    Let the rate at which Hilda works be x, and the rate at which Stan works be y, and the area of the lawn be A.

    What equations do you get? :smile:

    Job Completion Problem. Set up columns for rate, time, job; note that rate times time equals job.
    Set up rows for Stan, and for Hilda. The rate units will best be in jobs per minute. You will assume that the rates are additive when both Stan and Hilda work together.
