Stuck on this equation,need help

  1. May 19, 2007 #1
    If a first pump is used for 2.2 hours and a second pump is used used for 2.7 hours,32m cube can be removed from a waste water holding tank. If the first pump is used for 1.4 hours and the second pump used for 2.5 hours,24m cube can be removed. How much can each pump remove in 1 hour ?.
    What is the result to two significant digits ?

    This should be in the homework section, and it's not really a differential equation

    Start by writing down the speed of each pump (in meters cubed/hour), say v1 and v2. You should be able to write down two linear equations with these variables
