John takes 2 hours longer than Andrew to peel 400 pounds of apples. If together they can peel 400 pounds of apples in 7 hours, then how long would it take Andrew to peal the apples working alone? Please round your answer to three decimal places.

  • Math - ,

    This is a basic algebra problem. The 400 apples is irrelevant to the problem.

    J = John's time
    A = Andrew's time
    Here are the equations:

    J + A = 7
    A - 2 = J


    2A - 2 = 7
    2A=9
    A=4.50 hours, thus this is your answer.

    also J=2.50 hours.
